C++ code issue

Hi! iwrote a c++ simple program for practicing and im having a big issue. In the this simple program, the user set his name and his basketball habilities (between 0 and 100) and then his habilities are compared with the "othi"(the program player) habilities the issue: i used a function to the user set his habilities values, but i cant get this values back to the main function, Could you please tell me how can i make this program work? sorry by my english, thanks #include <iostream> #include <string> using namespace std; //Declaring all the functions void test(int a, int b); int test2(int x); int DATAp(int a, int b, int c, int z); //Player 1 variable declaration string Player1Name=""; int P1JumpQ=0; int P1shootingQ=0; int P1dribleQ=0; ; int main(){ //Player 2 variable declaration string Player2Name="Othi"; int P2JumpQ=75; int P2shootingQ=45; int P2dribleQ=70; int media2=(P2JumpQ+P2shootingQ+P2dribleQ)/3; //input cout<<"set your basketball player habilities\n set a number between 1 to 100\n"; cout<<"name: "; cin>> Player1Name; int media; // Im using a function (DATAp) to input the habilities value cout<< DATAp( P2JumpQ, P2shootingQ, P2dribleQ, media)<<endl; // im trying to test if the habilities value are the same in the main function media=(P1JumpQ+P1shootingQ+P1dribleQ)/3; cout<<"Your drible ability is= "<< P1dribleQ<<endl; cout<<"media provisoria= " <<media<<endl; //functions tests cout<<"the media of your player "<< Player1Name<<" is: "<< test2(media); test(media, media2); } // Cin all the habilities values int DATAp(int a, int b, int c, int d){ //Do while loop, for the user do not set a value greater than 100 do { cout<<"\nJump power (number<=100): "; cin>> a; //if that condition is true, break the loop if (a<100){ break; } }while (a>100); // If THIS while condition is true, restart the loop do{ cout<<"\nShoot

If your code is in your code section then please do it public. I cannot understand your code clearly

You mean when you take user input and than print its value it give you 0. like cout<<"Your drible ability is= "<< P1dribleQ<<endl; on above line you want to print value of P1dribleQ that is given by user input right? please reply

Check this, sorry I modified it a lot but I have to do it because of logical errors. It can be made more efficient though. #include <iostream> #include <string> using namespace std; //Declaring all the functions void test(int a, int b); void DATAp(); //Player 1 variable declaration (global variables) string Player1Name=""; int P1JumpQ=0; int P1shootingQ=0; int P1dribleQ=0; int media; int main(){ //Player 2 variable declaration string Player2Name="Othi"; int P2JumpQ=75; int P2shootingQ=45; int P2dribleQ=70; int media2=(P2JumpQ+P2shootingQ+P2dribleQ)/3; cout<<"Set your basketball player name: "; cin>> Player1Name; // Im using a function (DATAp) to input the habilities value DATAp(); cout<<"\n\nYour Jump power ability is= "<< P1JumpQ<<endl; cout<<"\nYour Shooting ability is= "<< P1shootingQ<<endl; cout<<"\nYour drible ability is= "<< P1dribleQ<<endl; cout<<"\n\nThe media of " << Player1Name << " is: " << media << endl; cout<<"\n\n" << Player2Name << " Jump power ability is= "<< P1JumpQ<<endl; cout<<"\n" << Player2Name << " Shooting ability is= "<< P1shootingQ<<endl; cout<<"\n" << Player2Name << " drible ability is= "<< P1dribleQ<<endl; //functions tests cout<<"\n\nThe media of " << Player2Name <<" is: "<< media2; test(media,media2); return 0; } // Cin all the habilities values void DATAp(){ //Do while loop, for the user do not set a value greater than 100 do { cout<<"\nJump power (number<=100): "; cin>> P1JumpQ; } while (P1JumpQ>100); // If THIS while condition is true, restart the loop do{ cout<<"\nShooting ability (number<=100): "; cin>> P1shootingQ; }while (P1shootingQ>100); do{ cout<<"\nDrible ability (number<=100): "; cin>> P1dribleQ; }while (P1dribleQ>100); // i sum all the values for then divide them by 3 media = (P1JumpQ + P1shootingQ + P1dribleQ)/3; } // Thi

program continued.... void test (int a, int b){ if(a > b){ cout<<"\n\n" << Player1Name << " was declared greater than othi."<<endl; } if(a == b){ cout<<"\n\n" << Player1Name << " was declared equal to othi."<<endl; } if(a < b){ cout<<"\n\n" << Player1Name << " was declared least than othi."<<endl; } } Can also find it here: https://code.sololearn.com/c0Ta95RIU6qY/#cpp

It was not appearing in main as you thought because you were not updating it's value in the DATAp function, so it remains 0 as you initialized it.

Thanks you a lot Mohammed Maaz i guess in this part it should be the player2 habilities cout<<"\n\n" << Player2Name << " Jump power ability is= "<< P2JumpQ<<endl; cout<<"\n" << Player2Name << " Shooting ability is= "<< P2shootingQ<<endl; cout<<"\n" << Player2Name << " drible ability is= "<< P2dribleQ<<endl; i would like to know if i shouldnt use parameters in the functions, i saw in your code that you didn't. Is this the why the user values were not on main?

No problem dude, you are always welcome! and the reason I didn't use the parameters is because there was no such need for them, as you have declared the variables globally. you can modify the program according to your needs anyway.

cout<<"Your drible ability is= "<< P1dribleQ<<endl; yeah, with this line i was just trying to test if the value given by the user appears on main, but doesnt because it prints 0
