Write a program in C using command line argument, take input as diameter of circle and calculate the area of circle.
Answer:
#include
#include
#define PI 3.142
int main(int argc, char * argv[])
{
float radius, area;
if(argc == 1 || argc > 2)
{
printf("Enter the diameter of circle\n");
exit(1);
}
radius = atoi(argv[1]) / 2;
area = PI * radius * radius ;
printf("Area of a circle = %5.2f\n", area);
}
