C language Nested loop Example
Example 1:
👇 आकृति प्रिंट करवाना
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *
* * * * * * * *
* * * * * * * * *
* * * * * * * * * *
#include <stdio.h>
#include <conio.h>
void main()
{
int a, b;
printf("\n\n\tnested loop for print '*' X 10 \n\n");
for (a = 1; a <= 10; a++)
{
for (b = 1; b <= a; b++)
{
printf(" * ");
}
printf("\n");
}
getch();
}
Output:-
nested loop for print '*' X 10
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *

Example 2:-
User से Row का इनपुट लेकर दो आकृति 👇 एक साथ प्रिंट करवाना:-
* * * * *
* * * * *
* * * * *
* * * * *
* * * * *
*
*
* *
* * *
* * * *
* * * * *
#include <stdio.h>
#include <conio.h>
void main()
{
int num, i, j;
printf("\n\n\tprint '*' \n\t Enter a Number : ");
scanf("%d", &num);
printf("\n\npress any key....");
getch();
printf("\n\t %d X %d\n\n", num, num);
for (i = 1; i <= num; i++)
{
for (j = 1; j <= num; j++)
{
printf(" * ");
}
printf("\n");
}
printf("\n\n\tnow we print ract angle\n\t press any key..... ");
getch();
printf("\n\n");
for (i = 1; i <= num; i++)
{
for (j = 1; j <= i; j++)
{
printf(" * ");
}
printf("\n");
}
getch();
}
Output:-
print '*'
Enter a Number : 6
press any key....
6 X 6
* * * * * *
* * * * * *
* * * * * *
* * * * * *
* * * * * *
* * * * * *
now we print ract angle
press any key.....

* * * * *
* * * *
* * *
* *
*
*
* *
* * *
* * * *
* * * * *
#include <stdio.h>
#include <conio.h>
void main()
{
int i, j, num;
printf("\n\n\t Enter a Number : ");
scanf("%d", &num);
printf("\n\n");
for (i = num; i >= 1; i--)
{
for (j = 1; j <= i; j++)
{
printf(" * ");
}
printf("\n");
}
for (i = 1; i <= num; i++)
{
for (j = 1; j <= i; j++)
{
printf(" * ");
}
printf("\n");
}
getch();
}
Output:-
Enter a Number : 6

Example 4 :-
User से Row का इनपुट लेकर आकृति 👇 प्रिंट करवाना:-
*<>*
*<>* *<>*
*<>* *<>* *<>*
*<>* *<>* *<>* *<>*
*<>* *<>* *<>* *<>* *<>*
<*_*) (*_*>
<*_*) (*_*> <*_*) (*_*>
<*_*) (*_*> <*_*) (*_*> <*_*) (*_*>
<*_*) (*_*> <*_*) (*_*> <*_*) (*_*> <*_*) (*_*>
<*_*) (*_*> <*_*) (*_*> <*_*) (*_*> <*_*) (*_*> <*_*) (*_*>
#include <stdio.h>
#include <conio.h>
void main()
{
int i, j, num;
printf("\n \n \t Enter a Number : ");
scanf("%d", &num);
for (i = 1; i <= num; i++)
{
for (j = 1; j <= num; j++)
{
if (j <= i)
{
printf("*<>* ");
}
else
{
printf("\t\t");
}
}
printf("\n");
}
for (i = 1; i <= num; i++)
{
for (j = 1; j <= num; j++)
{
if (j >= i)
{
printf("\t\t");
}
else
{
printf("<*_*)(*_*> ");
}
}
printf("\n");
}
getch();
}
Output:-
Enter a Number : 5
*<>*
*<>* *<>*
*<>* *<>* *<>*
*<>* *<>* *<>* *<>*
*<>* *<>* *<>* *<>* *<>*
style="text-align: left;"><*_*)(*_*>
<*_*)(*_*> <*_*)(*_*>
<*_*)(*_*> <*_*)(*_*> <*_*)(*_*>
<*_*)(*_*> <*_*)(*_*> <*_*)(*_*> <*_*)(*_*>
Example 5:-
User से एक number का इनपुट लेकर आकृति 👇 प्रिंट करवाना:-
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *
* * * * * * * *
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num, i, j;
cout << "\n\n\tEnter a Number : ";
cin >> num;
for (i = 1; i <= num; i++)
{
for (j = 1; j <= num; j++)
{
if (i <= (num - j))
{
cout << " ";
}
else
{
cout << " * ";
}
}
cout << endl;
}
getch();
return (0);
