why does this code output that there is an error because the else statement doesn't have a corresponding if statement?. How do i correct this?
#include <iostream>
using namespace std;
int main() {
int a;
for (int x =0; x<5;x++){
cin>>a;
if (a<1){
cout<<"a cannot be less than 1\n";
}
else if (a>10){
cout <<"a cannot be greater than 10\n";
}
}
else{
cout<<"code can run now"<<endl;
}
return 0;
}

jeez I don't understand this issue of indentation. I noticed that the instructions or methods that run within or outside a conditional are looped in a certain way. the way print() is indented affects what will be printed. pls who has any insight on this frustrating stuff

hey guys, I've been trying to work out the formula 'v=I*r'. But whenever I run the program and input values for I and r, it doesn't give the right answer.
This is the code
#include <iostream>
using namespace std;
int main() {
int i,r;
int v = i*r;
cout<<"what is the value of i?\n";
cin>>i;
cout<<"what is the value of r?\n";
cin>>r;
cout<<"voltage ="<<v<<endl;
return 0;
}
p/s: I'm new to programming

8 Réponsescan someone kindly correct me if i am wrong about this quote "As the program contains multiple lines of code, you should create it as a separate file and run it."
does that mean that if my code gets bigger it is advisable to create less line of codes but many files?

Is it possible to make my code run without having to press Enter on my IDE? For example: if I'm making a calculator and I want the calculations to be made as soon as I press "=" after typing the numbers and the operator?
Say I wanted to add two numbers: can it calculate automatically as soon as I write "2+3=" without having to press Enter?
