Arrays

Develop a program to implement the binary search algorithm. This technique compares the search key value with the value of the element that is midway in a "sorted" list. Then:
(a) If they match, the search is over.
(b) If the search key value is less than the middle value, then the first half of the list contains the key value.
(c) If the search keay value is greater than the middle value, then the second half contains the key value.
Repeat this "divide-and-conquer" strategy until we have a match. If the list is reduced to one no-matching element, then the list does not contain the key value. Use sorted list.

#include <stdio.h>
main()
{
int top,bottom,middle,value[50],key,n,i;
clrscr();
printf("Enter the number of elements in array:");
scanf("%d",&n);
printf("Enter the elements of array in ascending order\n");
for(i=1;i<=n;i++)
scanf("%d",&value[i]);
printf("Enter the value which you want to search:");
scanf("%d",&key);
top=n-1;
bottom=0;
do
{
middle=(top+bottom)/2;
if(value[middle]<key)
bottom=middle+1;
else
top=middle;
}
while(top>bottom);
if(top==-1)
printf("List is empty!");
else if(value[top]==key)
printf("value has been found!");
else
printf("Target value has not been found!");
getch();
}
OUTPUT
Enter the number of elements in array: 10
Enter the elements of array in ascending order
1 2 3 4 5 6 7 8 9 11
Enter the value which you want to search: 7
value has been found!

Enter the number of elements in array: 10
Enter the elements of array in ascending order
1 2 3 4 5 6 7 8 9 11
Enter the value which you want to search: 12
Target value has not been found!

Arrays

Selection sort is based on the follwing idea:
Selecting the largest array element and swapping it with the last array element leaves an unsorted list whose size is 1 less than the size of the original list. If we repeat this step again on the usorted list we will have an ordered list of size 2 and an unsorted list size n-2. When we repeat thist until the size of the unsorted list becomes one, the result will be a sorted list.
Write a program to implement this algorithm.

#include <stdio.h>
void main()
{
int i,j,min,pos,arr[200],size;
clrscr();
printf("Enter the number of elements of array:");
scanf("%d",&size);
printf("Enter the elements fo array\n");
for(i=1;i<=size;i++)
scanf("%d",&arr[i]);
for(i=1;iA<size-1;i++)
{
min=arr[i];
pos=i;
for(j=i+1;j<size;j++)
{
if(arr[j]<min)
{
min=arr[j];
pos=j;
}
}
arr[pos]=arr[i];
arr[i]=min;
}
for(i=1;i<=size;i++)
printf("%d ",arr[i]);
getch();
}

Lower right triangle with -1s
Right to left diagonal with zeros

#include <stdio.h>
main()
{
int a[10][10],i,j;
clrscr();
printf("This is 5x5 Matrix\n");
for(i=1;i<=5;i++)
{
for(j=1;j<=5;j++)
{
if(i+j<=5)
a[i][j]=+1;
else if(i+j>=7)
a[i][j]=-1;
else
a[i][j]=0;
printf("%3d",a[i][j]);
}
putchar('\n');
}
getch();

Two matrices that have the same number of rows and columns can be multiplied to produce a third matrix.The product of A and B is a third matrix C of size nxn where each elements of C is given by the following equation.
Cij = aikbkj

An election is contested by 5 candidates. The candidates are numbered 1 to 5 and the voting is done by marking the candidate number on the ballot paper. Write a program to read the ballots and count the votes cast fot each candidate using an array variable count. In case, a number read is outside the range 1 to 5, the ballot should be considered as a 'spoilt ballot' and the program should also count the number of spoilt ballots.

#include <stdio.h>
void main()

A survey to know the popularity of four cars (Ambassador, Fiat, Dolphin and Maruti) was conducted in four cities (Bombay, Calcutta, Delhi and Madras). Each person surveyed was asked to give his city and the type of car he was using. The results, in coded form, are tabulated as follows:
M 1 C 2 B 1 D 3 M 2 B 4
C 1 D 3 M 4 B 2 D 1 C 3
D 4 D 4 M 1 M 1 B 3 B 3
D1 C 2 B 3 M 1 B 1 C 2
D 3 M 4 C 1 D 2 M 3 B 4

Array

Write a program using a two-dimensional array to compute and print the following information from the table:
(a) Total value of sales by each girl.
(b) Total value of each item sold.
(c) Grand total of sales of all items by all girls.

#include <stdio.h>
#define     MAXGIRLS     4
#define     MAXITEMS     3
void main()
   {
       int   value[MAXGIRLS][MAXITEMS];
       int   girl_total[MAXGIRLS] , item_total[MAXITEMS];
       int   i, j, grand_total;
   /*.......READING OF VALUES AND COMPUTING girl_total ...*/
       printf("Input data\n");
       printf("Enter values, one at a time, row-wise\n\n");
       for( i = 0 ; i < MAXGIRLS ; i++ )
       {
   girl_total[i] = 0;
   for( j = 0 ; j < MAXITEMS ; j++ )
   {
      scanf("%d", &value[i][j]);
      girl_total[i] = girl_total[i] + value[i][j];
   }
       }
/*.......COMPUTING item_total..........................*/
       for( j = 0 ; j < MAXITEMS ; j++ )
       {
   item_total[j] = 0;
   for( i =0 ; i < MAXGIRLS ; i++ )
      item_total[j] = item_total[j] + value[i][j];
       }

/*.......COMPUTING grand_total.........................*/
       grand_total = 0;
       for( i =0 ; i < MAXGIRLS ; i++ )
   grand_total = grand_total + girl_total[i];
/* .......PRINTING OF RESULTS...........................*/
       printf("\n GIRLS TOTALS\n\n");
       for( i = 0 ; i < MAXGIRLS ; i++ )
   printf("Salesgirl[%d] = %d\n", i+1, girl_total[i] );
       printf("\n ITEM TOTALS\n\n");
       for( j = 0 ; j < MAXITEMS ; j++ )
   printf("Item[%d] = %d\n", j+1 , item_total[j] );
       printf("\nGrand Total = %d\n", grand_total);
       getch();

Arrays

Given below is the list of marks obtained by a class of 50 students in an annual examination.
43 65 51 27 79 11 56 61 52 09 25 36 07 49 55 63 74 81 49 37
40 49 16 75 87 91 33 24 58 78 65 56 76 67 45 54 35 63 12 21
73 49 51 19 39 49 68 93 85 59
Write a program to count the number of students belonging to each of following groups of marks: 0-9, 10-19, 20-29 .....100.

#include <stdio.h>
#define   MAXVAL    50
#define   COUNTER   11
void main()
   {
       float        value[MAXVAL];
       int          i, low, high;
       int   group[COUNTER] = {0,0,0,0,0,0,0,0,0,0,0};
/* . . . . . . . .READING AND COUNTING . . . . . .*/
       for( i = 0 ; i < MAXVAL ; i++ )
       {
/*. . . . . . . .READING OF VALUES . . . . . . . . */
   scanf("%f", &value[i]) ;
/*. . . . . .COUNTING FREQUENCY OF GROUPS. . . . . */
   ++ group[ (int) ( value[i] + 0.5 ) / 10] ;
       }
/* . . . .PRINTING OF FREQUENCY TABLE . . . . . . .*/
       printf("\n");
       printf(" GROUP     RANGE     FREQUENCY\n\n") ;
       for( i = 0 ; i < COUNTER ; i++ )
       {
   low = i * 10 ;
   if(i == 10)
     high = 100 ;
   else
     high = low + 9 ;
   printf(" %2d    %3d to %3d       %d\n",
    i+1, low, high, group[i] ) ;
       }
       getch();
   }

Arrays

Writ a program that uses a one-dimensional array x to read the values and compute the sum of their of their squares.

#include <stdio.h>
void main()
{
int i;
float x[10],value,total;
printf("ENTER 10 REAL NUMBERS\n");
for(i=0;i<10;i++)
{
scanf("%f",&value);
x[i]=value;
}
total=0.0;
for(i=0;i<10;i++)
total=total+x[i]*x[i];
printf("\n");
for(i=0;i<10;i++)
printf("x[%2d]=%5.2f\n",i+1,x[i]);
printf("\ntotal = %.2f\n",total);
getch();
}
