NPTEL programming in C - Printing Right Triangles

You are given a positive integer N. You have to print N rows as follows. The first row consists of one 0, the second row 2 zeroes, and so on, until the Nth row, which consists of N zeroes.

Note : NPTEL follows gcc compiler which doesn't supports conio.h package and it always to be started as int main() and should return a integer value

#include<stdio.h> int main() { int i,j,n; scanf("%d",&n); for(i=0;i<n;i++) { for(j=0;j<=i;j++) { printf("0"); } printf("\n"); } return 0; }
