#include<stdio.h>
#include<conio.h>
void main()
{
    int r, c, y;
    clrscr();
    r = 1;
    printf("The multiplication table is :\n\n");
    do
    {
        c = 1;
        do
        {
            y = r * c;
            printf("%5d", y);
            c = c + 1;
        } while(c <= 10);
        printf("\n\n");
        r = r + 1;
    } while(r <= 10);
    getch();
}

Output:

The multiplication table is :
1  2  3  4  5  6  7  8  9  10
