Q. Write a program to generate a following numbers triangle:
(Where user entered number through keyboard, for example if num=5).
| 1 | ||||
| 1 | 2 | |||
| 1 | 2 | 3 | ||
| 1 | 2 | 3 | 4 | |
| 1 | 2 | 3 | 4 | 5 |
Ans.
/*c program for number triangle pyramid*/
#include<stdio.h>
#include<conio.h>
int main()
{
int num,r,c,sp;
printf("Enter loop repeat number(rows): ");
scanf("%d",&num);
for(r=1; num>=r; r++)
for(r=1; num>=r; r++)
{
for(sp=num-r; sp>=1; sp--)
printf(" ");
for(c=1; c<=r; c++)
printf("%d",c);
printf("
");
");
}
getch();
getch();
return 0;
}
