Question

Need a little help after selecting choice 7 is still asking for size How do I fix that?




#include <iostream>
#include<iomanip>
using namespace std;


void printLine(int, int);//function prototype
void printTriangle1(int);//function prototype
void printTriangle2(int);//function prototype
void printTriangle3(int);//function prototype
void printTriangle4(int);//function prototype
void printDiagonalUp(int);//function prototype
void printDiagonalDown(int);//function prototype



void main()
{

do

cout << "6: Diagonal Down" << endl;
cout << "7: Quit" << endl;

cout << "Enter choice: ";
cin >> choice;


cout << "Enter size: ";
cin >> line;



if (choice == 1)
printTriangle1(line);
else if (choice == 2)
printTriangle2(line);
else if (choice == 3)

else

}
while(choice!=7);


}//end main

void printDiagonalUp(int numlines)
{

for (int line = 1; line <= numlines; line++)
{

}

}
void printDiagonalDown(int numlines)
{
int numstars, blanks;

numstars = 1;

for (int line = 1; line <= numlines; line++)
{

}

}

Explanation / Answer

its simple just observe the change i have made in if statement #include #includeusing namespace std; void printLine(int, int);//function prototype void printTriangle1(int);//function prototype void printTriangle2(int);//function prototype void printTriangle3(int);//function prototype void printTriangle4(int);//function prototype void printDiagonalUp(int);//function prototype void printDiagonalDown(int);//function prototype void main() { int line, choice; do { cout
