Display integrated pyramid star pattern in C using while loop

Display integrated pyramid star pattern in C using while loop

In this tutorial, we will discuss a concept of  Display integrated pyramid star pattern in C using while loop

In C  language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star patterns programs.

In this article, we are going to learn  how to Display integrated pyramid star pattern  using while loop in C  language

Display integrated pyramid star pattern in C

integrated Pyramid star pattern 1

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);  //get input from the user for rows
    i=1;
while(i<=rows){  //parent while loop
    j=i;
    while(j<=rows){  //print upper part of pattern
        printf("*");
        j++;
    }
    i++;
    printf("\n");
}

i=rows-1;
while(i>=1){   //print lower part of pattern
    j=i;
    while(j<=rows){
        printf("*");
        j++;
    }
    i--;
    printf("\n");
}
getch();
    return 0;
}

When the above code is executed, it produces the following results
