Program

#include<stdio.h>
int reverseInt(int num)
{
    int i,remainder,rev=0; 
    for(i=num;i>0; )
    {
        remainder=i%10;
        rev=rev*10+remainder;
        i=i/10;
    }
    return rev;
}
int main()
{
    int num;      
    printf("Enter an Integer: ");
    scanf("%d",&num);
    printf("Reversed number: %d", reverseInt(num));  
    return 0;  
}

Output

$ gcc reverse-integer-number-using-for.c
$ ./a.out
Enter an Integer: 57891
Reversed number: 19875
