Simple C program that calculates the factorial of any number:
#includeint main() { int fat, n; printf("Enter a value for which you want to calculate your factorial: "); scanf("%d", &n); for(fat = 1; n > 1; n = n - 1) fat = fat * n; printf("\nFactorial calculated: %d", fat); return 0; }
How does it work?
The variable “n” stores the number on which you want to calculate the factorial, the loop is executed, the variable “n” is multiplied by “fat”, so we have “fat = n” and at each iteration 1 unit is subtracted from the chosen number until it equals 1, i.e. the variable “fat” is multiplied at each iteration by the predecessor of the chosen number.
