    Number Guessing Game Help

    Below is my code for a number guessing game. The problem seems to be that if you guess the number on the first try it doesn't display "Phenomenal! You got it on your first try!" but instead skips to the next level. It wont generate a random number in this code but the number, the computer is always 'thinking of' is 1 so u can test it. Ty and please help

    #include<iostream>
    using namespace std;

    int main()
    {

    srand(time(0));

    cout << "The goal of this game is to guess the number I am thinking\n";

    Please use code tags when posting code to preserve indentation.
    Did you step through your program with the debugger and watch the values of your variables? If not, then you should do that first. Learning how to debug a program is part of learning how to program.

    - must #include <time.h> if want to use time()
    - must #include <string> if want to use string
    - if you define string m then you can not use cin >> m, it only works if you define m as character. Correct syntax is getline (cin, m);
    See getline and cin.getline for more info if you want to input a string.
    - some error with ; please correct

    this happened in ''level mode'' as your program is
    - number always is 1 because you did not generate a random number but define num =1 in your code, find and you will see , that why number always is 1.
    - it doesn't display "Phenomenal! You got it on your first try!" but instead skips to the next level
    because you put it in loop while(guess!=number) .... so that never got chance to be executed because it going to execute when you guessed it wrong

    - on ''practice mode'' - it doesn't work because of your wrong syntax when you use case() loop but I can see you did generate a random number, fix it

    You can use the stream operator with a string, but it will only read one word (up to the next whitespace). getline will read until the next newline character.
