I revamped one of my programs which used numerous "else if" statements.

Normally the user should press a number like 2 when asked if he wants to do another operation, and that would send a little message telling him to press enter to close the program. But it simply restarts the loop. What is wrong with this code?Code:#include <iostream> using namespace std; int addition ( int a, int b ); int substraction ( int c, int d ); int multiplication ( int e, int f); int division ( int g, int h); int end ( int k ); int main() { int i; int j = 1;//Might be modified at the end. int k; while ( j == 1 ) {//Is used to restart the program once a task is complete. cout<<"Please choose what type of mathematical operation you want to do:\n 1.Addition\n 2.Substraction\n 3.Multiplication\n 4.Division (might be imprecise)\n Any other number.End program\n"; cin>> i; cin.ignore(); switch ( i ) { case 1://This is the addition function. int a; int b; cout<<"Enter the two numbers to be added, pressing enter after each one: "; cin>> a >> b; cin.ignore(); cout<<"The result is: "<< addition ( a, b )<<"\n"; break; case 2://This is the substraction function. int c; int d; cout<<"Enter the two numbers to be substracted, pressing enter after each one: "; cin>> c >> d; cin.ignore(); cout<<"The result is: "<< substraction ( c, d )<<"\n"; break; case 3://This is the multiplication section. int e; int f; cout<<"Enter the two numbers to be multiplicated, pressing enter after each one: "; cin>> e >> f; cin.ignore(); cout<<"The result is: "<< multiplication ( e, f )<<"\n"; break; case 4: {//This is the division section. int g; int h; cout<<"Enter the two numbers to be divided, pressing enter after each one: "; cin>> g >> h; cin.ignore(); cout<<"The result is: "<< division ( g, h )<<"\n"; break; default: end ( k ); break; } } } cout<<"Thank you for using this program.\n Press enter to quit."; cin.get(); } int addition ( int a, int b ) { return a + b; } int substraction ( int c, int d ) { return c - d; } int multiplication ( int e, int f ) { return e * f; } int division ( int g, int h ) { return g / h; } int end ( int k ) {//This variable is used to modify j. int j; cout<<"Would you like to do another operation? Press 1 if you would like to, otherwise press any number: "; cin>> k; cin.ignore(); if ( k == 1) { j = 1;//Translation -> "The loop will start again." } else { j++;//Translation -> "The program will end." } }

By the way, sorry for posting the whole code, but I have no clue where the problem is.
