I've looked through many old posts and have not seen one like this. I know creating a triangular shape composed of *'s is common, but this one's a little different.
This is how the output should look:
1
12
123
1234
123
12
1
I have tried to write some code, but I substituted *'s for numbers to see if I could get that to work first. As usual, it's not working. Could anyone give me some idea where I'm going wrong. Thanks.
Code:#include <iostream> using namespace std; //Functions prototypes... void instructions (); int triangle (); //---------------------------------- int main () { instructions (); triangle (); return 0; } //-------------------------------------------------------------------------- // User instructions void instructions () { cout << "This program displays the numbers 1 through 4 " << "in incremental steps, " << endl; cout << "starting with just 1 on the first line " << "and increasing each line by one digit " << endl; cout << "until the fourth line has all 4 numbers. " << "It then starts displaying the numbers" << endl; cout << "in decremental steps until the final line " << "just displays the number 1." << endl << endl; } // End of instructions function //----------------------------------------------------------------- int triangle () { //Local variables: int horiz=0; int vert=0; for(int vert=1; vert<=4; vert++) { for(int horiz=1; horiz<=3; horiz++) cout << "*"; { for(int horiz=1;horiz<=vert; horiz++) cout << "*"; } cout << endl; } return 0; }
