Program gone crazy....

[JR]

well sort of. the program should do addition subtraction and multiplication to 2 random numbers, and it depends on the users choice. The user gets 5 questions per choice and then if he answers them right from the first time he gets 10 points if not he has 2 more tries which he gets 5 points for the first and 2 points for the third. if the question was answered wrong he gets no points and the program moves on to the next question ouf of 5.

for starterts i got and endless loop dont know why, if i type the wrong answer in then it gives the error msg and gives u 3 tries but it gives u endless amount of questions and i only need 5. If i get the answer right the program still gives u 3 tries eventhough u got it right.... i cant exit the program when i press 4 theres an endless loop... how to fix this stuff?


Now heres my code: Note( only try it with addtion cause i didnt do it for the other 2, gotta make addition work properly first)

code:

//Alex R //A5Q1 //October 5th #include <iostream.h > #include <stdlib.h> #include <time.h> //menu int menu() { int choice; cout<<"Enter your choice\n"; cout<<"1. Addition\n2. Subtraction\n3. Multiplication\n4. Quit\n"; cin>>choice; return (choice); } //random function int ran () { int x; x=rand() % 100; return (x); } //function for addition int add (int a,int b) { return(a+b); } //function for subtraction int subtract (int a,int b) { return(a-b); } //Function for multiplication int multiply (int a,int b) { return (a*b); } //Answer calculation function int answers(int a,int b,int choice) { //int answer; int answer,userans,wrong,points,question,total; wrong=0; points=10; total=0; question=0; int x,y; while (wrong<3){ while (question<5){ start: switch (choice){ case 1:cout<<a<<" + "<<b<<" = "<<endl; answer=add(a,b); cin>>userans; if (answer!=userans && wrong==0){ cout<<"You have used 1 try out of 3, you can only get 5 points now\n"; points=5; wrong++; } cout<<a<<" + "<<b<<" = "<<endl; cin>>userans; if (answer!=userans && wrong==1){ cout<<"You have used 2 try out of 3, you can only get 2 points now\n"; points=2; wrong++; } cout<<a<<" + "<<b<<" = "<<endl; cin>>userans; if (answer!=userans && wrong==2){ cout<<"You have used 3 try out of 3, You get 0 points\nthe correct answer is "<<answer<<endl; points=0; wrong++; question++; a=ran(); b=ran(); wrong=0; goto start; } if (answer=userans){ points=10; question++; a=ran(); b=ran(); break; goto start; } case 2:cout<<a<<" - "<<b<<" = "<<endl; subtract(a,b) ; break; case 3:cout<<a<<" * "<<b<<" = "<<endl; multiply (a,b); break; case 4: cout<<"Bye!!"; break; default:cout<<"The options are only 1-4."; break; } } } } int main () { srand(time(0)); int x,y; x=ran(); y=ran(); answers(x,y,menu()); return 0; }

your code is a mess... first off, you have no indents, second, your spacing is really off... and your code is way too complicated... i wrote a basic form of what u want to do in 5 min.. it doesnt have that point stuff u wanted.. but im not gona do all ur hw for you... copy it if u want, but i suggest understanding it and writing ur own

code:

#include <iostream.h > #include <stdlib.h> #include <time.h> int menu(){         int choice;         cout<<"Enter your choice\n";         cout<<"1. Addition\n2. Subtraction\n3. Multiplication\n4. Quit\n";         cin>>choice;         return choice; } int operation (int a,int b, int choice){         if (choice == 1)                 return a + b;         else if (choice == 2)                 return a - b;         else                 return a * b; } void answers (int x, int y, int choice) {         int num;         if (choice == 4)                 return;         while(1)         {                 if (choice == 1){                         cout << "what is "<<x<<"+"<<y<<"?\n";                         cin >> num;                 }                 else if (choice == 2){                         cout << "what is "<<x<<"-"<<y<<"?\n";                         cin >> num;                 }                 else if (choice == 3){                         cout << "what is "<<x<<"x"<<y<<"?\n";                         cin >> num;                 }                 if (num == operation(x,y,choice)){                         cout<<"right\n";                         break;                 }                 else                         cout<<"wrong\n";         } } int main (){         srand(time(0));         int x,y;         x = rand() % 100;         y = rand() % 100;         answers(x,y,menu());         return 0; }

sry.. forgot to put the loop in there, i edited it in now
