Managing Input and Output Operations

Reliability Graph
Problem: The reliability of an electronic component is given by relibility (r) = power -LAMBDA t of e
where LAMBDA is the component failure rate per hour and t is the time of operation in hours. A graph is
required to determine the reliability at various operating times, from 0 to 3000 hours. The failure rate LAMBDA is 0.001.

#include <math.h>

#include <stdio.h>
#define LAMBDA 0.001
void main()
{
double t;
float r;
int i,R;
for(i=1;i<=27;++i)
{
printf("--");
}
printf("\n");
for(t=0;t<=3000;t+=150)
{
r=exp(-LAMBDA*t);
R=(int)(50*r+0.5);
printf(" |");
for(i<=1;i<=R;++i)
{
printf("*");
}
printf("#\n");
}
for(i=1;i<3;++i)
{
printf(" |\n");
}
getch();
}
