Write a program to Print pyramid of numbers using loops in c?

Answer 1

#include <stdio.h>

#include <conio.h>

void main()

{

int height, line, i;

clrscr();

scanf("%d", &height);

for (i = 0; i < height - 1; ++i)

printf(" ");

printf("1\n");

for (line = 1; line < height; ++line)

{

for (i = 0; i < height - line - 1; ++i)

printf(" ");

for (i = 0; i < line; ++i)

printf("%d", line + 1);

printf(" ");

for (i = 0; i < line; ++i)

printf("%d", line + 1);

printf("\n");

}

getch();

}

Answer 2

#include<stdio.h>

#include<conio.h>

void main()

{

int i,j,n;

clrscr();

i=j=0;

printf("enter the value of n");

scanf("%d",&n);

for(i=1;i<=n;i++)

{

for(j=1;j<=n;j++)

{

printf("%d\n",i,j);

i=i+1;

}

}

getch();

}

Answer 3

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) { for(space=1;space<=rows-i;++space) { printf(" "); } while(k!=2*i-1) { printf("* "); ++k; } k=0; printf("\n"); } return 0;}

Answer 4

public class whileloop

{

public static void main (String args[])

{

int a=1;

while(a<=5)

{

int b=1;

while(b<=a)

{System.out.print(b);

b++;

}

System.out.println();

a++;

}

}

}
