#include <iostream> using namespace std; int main() { int i; for (i = 1; i <= 5; ++i) // set the total "number of digits in each row" (e.g. row1 one digit, row2 two digits, row3 three digits and so on) { for (int j = 1; j <= i; ++j) { // handles the "number of prints (column)" based upon the current value of i cout << i; // prints out the value of i } cout << "\n"; // break the line upon completion of each row } return 0; } 1 22 333 4444 55555

Increase j by one. Basically, j gets incremented when the program flow reaches to the right curly brace as for (int j = 1; j <= i; ++j) { } // here, j gets incremented after each loop cycle

n = 15 # size for x in range(n//2,n + 1,+2): for y in range(1,n - x,+2): print(" ",end="") for y in range(1,x + 1): print("*",end="") for y in range(1,n - x + 1): print(" ",end="") for y in range(1,x + 1): print("*",end="") print() for x in range(n, 0,-1): for y in range(x, n): print(" ",end="") for y in range(1,(x * 2)): print("*",end="") print() print("heart")

I think the output will be like this : 1 22 333 4444 55555 Explanation : In First iteration a new line and 1 from j (checks j(1)<=i(1)) will be executed In Second iteration a new line and 22 from j (checks j(1)<=i(2) ie., checks 2 times inside second loop until the condition (j<=i) becomes false) will be executed inside the second for loop In Third iteration a new line and 333 from j (checks j(1)<=i(3) ie., checks 3 times inside second loop until the condition (j<=i) becomes false) will be executed inside the second for loop In Fourth iteration a new line and 4444 from j (checks j(1)<=i(4) ie., checks 4 times inside second loop until the condition (j<=i) becomes false) will be executed inside the second for loop In Fifth iteration a new line and 55555 from j (checks j(1)<=i(5) ie., checks 5 times inside second loop until the condition (j<=i) becomes false) will be executed inside the second for loop After both the loops becomes false the execution of the program terminates

"j is the value of digits" No, the number of digits for printing out. `j` in the inner loop is responsible for iterating till the current value of `i` and provides the correct number of cycles over the `cout << i;`. For example, if the i = 3 in the outer loop, it says to the inner loop "iterate from 1 to 3 over cout << 3", so, in this particular iteration, the output would be as 333
