| Increased Number Triangle Posted: 01 Sep 2013 04:44 AM PDT Q. Write a C program to print the following Increased Number Triangle as:
5 45 345 234512345
Ans.
/*c program for increased number triangle*/#include<stdio.h>int main(){ int num,r,n,sp; printf("Enter no. of rows : "); scanf("%d", &num); for(r=1; r<=num; r++) { for(sp=num-r; sp>=1; sp--) printf(" "); for(n=num-r+1; n<=num; n++) printf("%d",n); printf("\n"); } getch(); return 0;}
The output of above program would be:
