#include <stdio.h> #include <math.h> // C program to print the heart star pattern int main() { // set output size int size = 10; for (int x = 0; x < size; x++) { for (int y = 0; y <= 4*size; y++) { double dist1 = sqrt(pow(x - size, 2) + pow(y - size, 2)); double dist2 = sqrt(pow(x - size, 2) + pow(y - 3*size, 2)); if (dist1 < size + 0.5 || dist2 < size + 0.5) { printf("*"); } else { printf(" "); } } printf("\n"); } for (int x = 1; x < 2*size; x++) { for (int y = 0; y < x; y++) { printf(" "); } for (int y = 0; y < 4*size + 1 - 2*x; y++) { printf("*"); } printf("\n"); } return 0; } |

Output:
We can also modify the above code to print the heart pattern with the desired text inside.

Output:
