calculate factorial in c code example
Example 1: factorial c program using for loop
#include
int main(){
int i,f=1,num;
printf("Enter a number: ");
scanf("%d",&num);
for(i=1;i<=num;i++)
f=f*i;
printf("Factorial of %d is: %d",num,f);
return 0;
}
Example 2: factorial of a given number in c
//Factorial of a given number
#include
//This function returns factorial of the number passed to it
long int factorialOf(int number){
long int factorial = 1;
while(number){
factorial*=number;
number-=1;
}
return factorial;
}
int main(void) {
int n;
printf("Find factorial of \n");
scanf("%d",&n);
printf("\nThe factorial of %d is %ld",n,factorialOf(n));
return 0;
}
Example 3: c code factorial function
#include
int fact(int);
void main()
{
int no,factorial;
printf("Enter a number to calculate it's factorial\n");
scanf("%d",&no);
factorial=fact(no);
printf("Factorial of the num(%d) = %d\n",no,factorial);
//printf("Factorial of the num(%d) = %d\n",no,fact(no));//another way of calling a function//comment above two lines if you want to use this
}
int fact(int n)
{
int i,f=1;
for(i=1;i<=n;i++)
{
f=f*i;
}
return f;
}
