Jayakrishna🇮🇳 thanks and your explanation is wonderful I understood everything 😌

Answer 2

//Working code ..
//but it may modified to better by taking class variable instead of global variables... You have infinite loop, make it to limited.
//Read comments.. and reply if anything is not understandable....

#include<iostream>
#include<cstdlib>
#include<ctime>
using namespace std;
int r_num1,r_num2,score=0,life=3;
class ran{
public:
void random()
{
r_num1=1+(rand()%6);
r_num2=1+(rand()%6);
}
/*int life(){
public:
life--;
return life;
}*/
void rscore(){ //already used score as variable name so I changed function name..
//public: //its not valid here to put.
score+=1;
}
};
int main()
{
int ans,c_ans;
srand(time(0));
ran o;
while(true){
o.random();
c_ans=r_num1+r_num2;
cout<<r_num1<<"+"<<r_num2<<"="<<endl;
cin>>ans;
if(ans==c_ans)
{
o.rscore(); // it wont returning anything so just call like this
cout<<"score:"<<score<<endl;
}
break;//to terminate loop, instead loop limited times by a counter variable.
}
return 0;
}
