Question

Alright, I have a question, I veered away from using strings for selection so now I use an integer. When the user enters a number then the game progresses. If they enter a wrong character it SHOULD give the else statement, however if I enter a letter or character the system goes into an endless loop effect then crashes. Is there a way to give the else statement even if the user defines the variable’s type.

// action variable;
int c_action: 

if (c_action == 1){
    // enemy attack and user attack with added effect buffer. 
    ///////////////////////////////////////////////////////
    u_attack = userAttack(userAtk, weapons);
    enemyHP = enemyHP - u_attack;

    cout << " charging at the enemy you do " << u_attack << "damage" << endl;
    e_attack = enemyAttack(enemyAtk);
    userHP = userHP - e_attack;
    cout << "however he lashes back causing you to have " << userHP << "health left "  << endl << endl << endl << endl;
    //end of ATTACK ACTION
}else{
    cout << "invalid actions" << endl;
    goto ACTIONS;
}

Your problem is not with the else-statement, but with your input. If you do something like

cin >> i;

and enter a character, the streams error state is set and any subsequent try to read from the stream will fail unless you reset the error state first.

You should read a string instead and convert the strings contents to integer.
