Scand("%d",&num);
for(i=1;i<=num;i++)
fact*=i;
printf(“%d”, fact);
}
12.Write a c program to reverse a given string without using string library function.
#include <conio.h>#include <stdio.h>void main(){ int i,j,len=0; char str[50],revstr[50]; printf("\n Enter a String to Reverse : " ); gets(str); for(i=0; str[i]!='\0'; i++) { len++; } j=0; for(i=len-1; i>=0; i--) { revstr[j++]=str[i]; }printf("\n Reverse of the Given String is: %s",revstr); getch();}13.Write a c program to swipe 2 numbers by using functions with argument but not return type.
#include<stdio.h>
void swap(int, int);
int main()
{
int a, b;
printf("Enter values for a and b\n");
scanf("%d%d", &a, &b);
