Write a C++ Programs To Create Pyramid and Pattern
PROGRAM: C++ Programs To Create Pyramid and Pattern
/* C++ Programs To Create Pyramid and Pattern */
1 : Program to Print a Half-Pyramid Using *
#include <iostream>
using namespace std;
int main() {
int rows;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = 1; i <= rows; ++i) {
for(int j = 1; j <= i; ++j) {
cout << “* “;
}
cout << “\n”;
}
return 0;
}
2: Program to Print a Half-Pyramid Using Numbers
#include <iostream>
using namespace std;
int main() {
int rows;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = 1; i <= rows; ++i) {
for(int j = 1; j <= i; ++j) {
cout << j << ” “;
}
cout << “\n”;
}
return 0;
}
3: Program to Print Half-Pyramid Using Alphabets
#include <iostream>
using namespace std;
int main() {
char input, alphabet = ‘A’;
cout << “Enter the uppercase character you want to print in the last row: “;
cin >> input;
// convert input character to uppercase
input = toupper(input);
for(int i = 1; i <= (input-‘A’+1); ++i) {
for(int j = 1; j <= i; ++j) {
cout << alphabet << ” “;
}
++alphabet;
cout << endl;
}
return 0;
}
4: Inverted Half-Pyramid Using *
#include <iostream>
using namespace std;
int main() {
int rows;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = rows; i >= 1; –i) {
for(int j = 1; j <= i; ++j) {
cout << “* “;
}
cout << endl;
}
return 0;
}
5: Inverted Half-Pyramid Using Numbers
#include <iostream>
using namespace std;
int main() {
int rows;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = rows; i >= 1; –i)
{
for(int j = 1; j <= i; ++j)
{
cout << j << ” “;
}
cout << endl;
}
return 0;
}
6: Program to Print a Full Pyramid Using *
#include <iostream>
using namespace std;
int main() {
int space, rows;
cout <<“Enter number of rows: “;
cin >> rows;
for(int i = 1, k = 0; i <= rows; ++i, k = 0) {
for(space = 1; space <= rows-i; ++space) {
cout <<” “;
}
while(k != 2*i-1) {
cout << “* “;
++k;
}
cout << endl;
}
return 0;
}
7: Program to Print a Pyramid Using Numbers
#include <iostream>
using namespace std;
int main() {
int rows, count = 0, count1 = 0, k = 0;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = 1; i <= rows; ++i) {
for(int space = 1; space <= rows-i; ++space) {
cout << ” “;
++count;
}
while(k != 2*i-1) {
if (count <= rows-1) {
cout << i+k << ” “;
++count;
}
else {
++count1;
cout << i+k-2*count1 << ” “;
}
++k;
}
count1 = count = k = 0;
cout << endl;
}
return 0;
}
8: Inverted Full Pyramid Using *
#include <iostream>
using namespace std;
int main() {
int rows;
cout << “Enter number of rows: “;
cin >> rows;
for(int i = rows; i >= 1; –i) {
for(int space = 0; space < rows-i; ++space)
cout << ” “;
for(int j = i; j <= 2*i-1; ++j)
cout << “* “;
for(int j = 0; j < i-1; ++j)
cout << “* “;
cout << endl;
}
return 0;
}
