This article is aimed at giving a C++ implementation for pattern printing.
// C++ code to demonstrate star pattern #include <iostream> using namespace std; // Function to demonstrate printing pattern void pypart(int n) { // outer loop to handle number of rows // n in this case for (int i=0; i<n; i++) { // inner loop to handle number of columns // values changing acc. to outer loop for(int j=0; j<=i; j++ ) { // printing stars cout << "* "; } // ending line after each row cout << endl; } } // Driver Function int main() { int n = 5; pypart(n); return 0; } |
Output:
* * * * * * * * * * * * * * *
// C++ code to demonstrate star pattern #include <iostream> using namespace std; // Function to demonstrate printing pattern void pypart2(int n) { // number of spaces int k = 2*n - 2; // outer loop to handle number of rows // n in this case for (int i=0; i<n; i++) { // inner loop to handle number spaces // values changing acc. to requirement for (int j=0; j<k; j++) cout <<" "; // decrementing k after each loop k = k - 2; // inner loop to handle number of columns // values changing acc. to outer loop for (int j=0; j<=i; j++ ) { // printing stars cout << "* "; } // ending line after each row cout << endl; } } // Driver Function int main() { int n = 5; pypart2(n); return 0; } |

// C++ code to demonstrate printing pattern of numbers #include <iostream> using namespace std; // Function to demonstrate printing pattern void numpat(int n) { // initialising starting number int num = 1; // outer loop to handle number of rows // n in this case for (int i=0; i<n; i++) { // inner loop to handle number of columns // values changing acc. to outer loop for (int j=0; j<=i; j++ ) { // printing number cout << num << " "; // incrementing number at each column num = num + 1; } // ending line after each row cout << endl; } } // Driver Function int main() { int n = 5; numpat(n); return 0; } |

// C++ code to demonstrate printing pattern of alphabets #include <iostream> using namespace std; // Function to demonstrate printing pattern void alphapat(int n) { // initializing value corresponding to 'A' // ASCII value int num = 65; // outer loop to handle number of rows // n in this case for (int i=0; i<n; i++) { // inner loop to handle number of columns // values changing acc. to outer loop for (int j=0; j<=i; j++ ) { // explicitly converting to char char ch = char(num); // printing char value cout << ch << " "; } // incrementing number num = num + 1; // ending line after each row cout << endl; } } // Driver Function int main() { int n = 5; alphapat(n); return 0; } |
Output:
