Program: 38

Write a C program to display whether number is prime or not (while-loop).

#include #include float square(float); int main() { float a, b; printf("Enter any number: "); scanf("%f", &a); b=square(a); printf("Square of %f is %f\n",a,b); getch(); } float square (float x) { float y; y=x*x; return(y); }
Output
`Enter any number: 5` `Square of 5.000000 is 25.000000`

#include
float square(float);
int main()
{
    float a, b;
    printf("Enter any number: ");

    b=square(a);
    printf("Square of %f is %f\n",a,b);
    getch();
}

float square (float x)

{

    float y;

    y=x*x;
