To print a Diamond Pattern in C++, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printDiamond
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from 1 to n
and the inner loops control the spaces and stars in each row.#include <iostream>
#include <string>
void printDiamond(int n) {
for (int i = 1; i <= n; i++) {
std::string spaces(n - i, ' ');
std::string stars(2 * i - 1, '*');
std::cout << spaces << stars << std::endl;
}
for (int i = n - 1; i > 0; i--) {
std::string spaces(n - i, ' ');
std::string stars(2 * i - 1, '*');
std::cout << spaces << stars << std::endl;
}
}
int main() {
printDiamond(5);
return 0;
}
