im just learning c++, and working on my small project minicalculator, for some reason when i add any two numbers i get answer like 121545123157 instead of a real answer which is 10 or 20. If you can find any errors in my code il be apreciated

Code: Show/Hide /*my first program after not pragraming for a year ShellExecute(NULL, "open", "http://a3studio.4t.com", NULL, NULL, SW_SHOWNORMAL); this command brings u to this website */ #include <iostream> #include <stdlib.h> #include <windows.h> using namespace std; #define PI 3.14 //defines pi so pie now = to 3.14 int main() {     SetConsoleTitle("Mini Calculator");  // title     SetCursorPos(0,0);                    //cursor position         HANDLE text;                              //handle variable     text = GetStdHandle(STD_OUTPUT_HANDLE);     //make it that     SetConsoleTextAttribute(text,FOREGROUND_GREEN); //text attribute         menu:         int choice;     cout<<"Welcome to MiniCalculator \n\n";     cout<<"Type in 1 and press enter to add"<<endl;     cout<<"Type in 2 and press enter to subtract"<<endl;     cout<<"Type in 3 and press enter to multiply"<<endl;     cout<<"Type in 4 and press enter to divide"<<endl;     cout<<"Type in 5 and press enter to find area/perimiter of a circle"<<endl;     cout<<"Type in 6 and press enter to go to google.com"<<endl;     cout<<"Type in 7 and press enter to exit"<<endl;     cout<<"Type in your choice and press enter: ";     cin>>choice;         switch (choice){            case 1:                 int a;                 int b;                 int c;                                 c = a + b;                                 cout<<"\n\n Type in and press enter the number you want to add to: ";                 cin>>a;                 cout<<"\n\n Now type in and press enter the number you want to add: ";                 cin>>b;                 cout<<"The Result is "<<c<<".\n\n\n\n";                 system("pause");                 cout<<"n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n";                 goto menu;                 }                                                 return 0;                 }                                         [quote][/quote]

c++ programs are executed in order, one line at a time. So when you do "c = a + b" it takes whatever is in a and b at that point in the program and stores in in c.

so doing something like

Code: Show/Hide c = 5; c=10; cout << c;

is perfectly legal and would print out 10. The program first puts 5 into c, then 10, then prints out c, which is 10.

basically what he is saying is that you have to move this line:

c = a + b;

after you input a and b. and then you output c.
