This is a simple C Program which prints out a Right angled triangle with respect to he input given.

Right angled triangle

PROGRAM :

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i, j, n,k;
    printf("Enter number of lines[height of triangle] : \t");
    scanf("%d",&n);
    for(i=1; i<=n; i++)
    {
        for(j=i; j<n; j++)
        {
            printf(" ");
        }
        for(k=1; k<(i*2); k++)
        {

            printf("%d",k++);
        }
        printf("\n");
    }
    return 0;
}

OUTPUT : 

C Program to print  Right angled triangle

NOTE : The output should be less than 5 to see the best result as when the output exceeds 5 the numbers from 10,11 .. are 2 digits so then the output would become somewhat messy.
