C Program to Print Rhombus Star Pattern

Write a C Program to Print Rhombus Star Pattern using for loop. The main loop in this c example iterates from the last row to first and nested for loops prints the rhombus pattern.

#include<stdio.h>
int main()
{
    int i, j, k, rows;
    printf("Enter Rhombus Star Pattern Rows =  ");
    scanf("%d", &rows);

    printf("Rhombus Star Pattern\n");
    for(i = rows; i >= 1; i--)
    {
        for(j = 1; j <= i - 1; j++)
        {
            printf(" ");
        }
        for(k = 1; k <= rows; k++)
        {
            printf("*");
        }         
        printf("\n");   
    }
    return 0;
}

This C Program allows entering a symbol and prints that symbol in Rhombus Pattern.

#include<stdio.h>
int main()
{
    int i, j, k, rows;
    char ch;
    
    printf("Symbol for Rhombus Pattern =  ");
    scanf("%c", &ch);

    printf("Enter Rhombus Star Pattern Rows =  ");
    scanf("%d", &rows);

    printf("Rhombus Star Pattern\n");
    i = rows;
    while(i >= 1)
    {
        j = 1;
        while(j <= i - 1)
        {
            printf(" ");
            j++;
        }
        k = 1;
        while(k <= rows)
        {
            printf("%c", ch);
            k++;
        }         
        printf("\n"); 
        i--;  
    }
    return 0;
}

Output

Symbol for Rhombus Pattern =  #
