Printing Heart Pattern in C

In this program we will see how to print heart shaped pattern in C. The heart shape pattern consists of two rounded peaks at the top and an inverted triangle forming the base.

Now if we analyze this pattern, we can find different sections. The base of the heart is an inverted triangle; the upper portion has two different peaks with a gap between them. To make this pattern we have to manage these parts into our code −

Syntax

// Heart pattern logic:
// 1. Upper part: Two peaks with gap
// 2. Lower part: Inverted triangle

Example

#include <stdio.h>

int main() {
    int a, b, line = 12;
    
    // For the upper part of the heart
    for (a = line/2; a <= line; a = a+2) {
        // Create space before the first peak
        for (b = 1; b < line-a; b = b+2)
            printf(" ");
        
        // Print the first peak
        for (b = 1; b <= a; b++)
            printf("*");
        
        // Create space between peaks
        for (b = 1; b <= line-a; b++)
            printf(" ");
        
        // Print the second peak
        for (b = 1; b <= a-1; b++)
            printf("*");
        
        printf("<br>");
    }
    
    // The base of the heart is inverted triangle
    for (a = line; a >= 0; a--) {
        // Generate space before triangle
        for (b = a; b < line; b++)
            printf(" ");
        
        // Print the triangle
        for (b = 1; b <= ((a * 2) - 1); b++)
            printf("*");
        
        printf("<br>");
    }
    
    return 0;
}

Output

How It Works

• Upper Part: Creates two peaks with calculated spacing between them using nested loops.
• Lower Part: Forms an inverted triangle by decreasing the number of stars in each row.
• Spacing: Uses appropriate spaces to center the pattern and create the heart shape.

Conclusion

The heart pattern in C combines two main parts − the upper curved section with two peaks and the lower inverted triangle. Proper spacing and loop control create the distinctive heart shape.
