I have a question

general
1

Row = 5, Col = 8;
for(int i=0;i<Row;i++)
{
for(int j=0;j<Col;j++)
{
//Print 0 to 40, just by using i and j, don’t use any variables.
}
}

you can use the formula (i*Col+j) for each iteration and get your desired output.

This one is definitely working but I need to do it just by using i and j. No variables inside.

i and j are variables too!

public class Main
{
	public static void main(String[] args) {
        int Row = 5;
        int Col = 8;
	    for(int i = 0 ; i<Row ;i++){
	        if(i == 4) {
	             System.out.print("40");
	            break;}
	        for(int j = 0 ;j<=Col;j++){
	            System.out.print(i+""+j+" ");
	          
	        }
	        System.out.print(i+""+9);
	        System.out.println();
	    }
	}
}

By using this technique you can get 0-40 notice we have not used any internal variable just used if else syntax.

#include <iostream>

int main() {
    int Row = 5, Col = 8;

    for (int i = 0; i < Row; i++) {
        for (int j = 0; j < Col; j++) {
            std::cout << 8 * i + j << " ";
        }
    }
    std::cout << 40;

    return 0;
}

python
row =5
col=8
for i in range(row):
for j in range(1,col+1):
print(col*i + j)

8

include

int main() {
int Row = 5;
int Col = 8;

for (int i = 0; i < Row; i++) {
    for (int j = 0; j < Col; j++) {
        int value = i * Col + j;
        std::cout << value << " ";
    }
    std::cout << std::endl;  // Move to the next line after each row
}

return 0;

}
