Program to print triangle numbers pattern in c; Through this tutorial, we will learn how to print triangle numbers pattern in c programs using for loop and while loop.
Programs to Print Triangle Numbers Pattern in C
- C Program to Print Triangle Numbers Pattern using For Loop
- C Program to Print Triangle Numbers Pattern using While Loop
C Program to Print Triangle Numbers Pattern using For Loop
#include<stdio.h>
#include<stdlib.h>
int main(){
int i,j,k,l,n;
printf("enter the range=");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
for(j=1;j<=n-i;j++)
{
printf(" ");
}
for(k=1;k<=i;k++)
{
printf("%d",k);
}
for(l=i-1;l>=1;l--)
{
printf("%d",l);
}
printf("\n");
}
return 0;
}
The output of the above c program; is as follows:
enter the range=5
1
121
12321
1234321
123454321
C Program to Print Triangle Numbers Pattern using While Loop
#include <stdio.h>
int main() {
int i, space, rows, k = 0;
printf("Enter the number of rows: ");
scanf("%d", &rows);
for (i = 1; i <= rows; ++i, k = 0) {
for (space = 1; space <= rows - i; ++space) {
printf(" ");
}
while (k != 2 * i - 1) {
printf("%d ", k);
++k;
}
printf("\n");
}
return 0;
}
The output of the above c program; is as follows:
Enter the number of rows: 5
0
0 1 2
0 1 2 3 4
0 1 2 3 4 5 6
0 1 2 3 4 5 6 7 8
