Q. Write a function fact to calculate the factorial value of any number.
Ans.
/*c program for make function fact to calculate factorial value of any number*/
#include<stdio.h>
int fact(int );
int main()
{
int num,f;
printf("Enter any number : ");
scanf("%d", &num);
f = fact(num);
printf("Factorial value of %d is %d",num,f);
return 0;
}
int fact(int n)
{
int z=1;
for(; n>=1; n--)
z = z * n;
return(z);
}
The output of above program would be:
/*c program for make function fact to calculate factorial value of any number*/
#include<stdio.h>
int fact(int );
int main()
{
int num,f;
printf("Enter any number : ");
scanf("%d", &num);
f = fact(num);
printf("Factorial value of %d is %d",num,f);
return 0;
}
int fact(int n)
{
int z=1;
for(; n>=1; n--)
z = z * n;
return(z);
}
The output of above program would be:

why to return(z);
ReplyDeletez store the value of factorial, so according to program we want the display the result of factorial hence we used z
