A Rust beginner might be tempted to declare a global variable exactly like any other variable in Rust, usinglet. The full program could then look like this: usechrono::Utc;letSTART_TIME=Utc::now().to_string();pubfnmain(){letthread_1=std::thread::spawn(||{println!("Started {}, call...
In C, we cannot access a global variable if we have a local variable with same name, but it is possible in C++ using scope resolution operator (::). 1#include<iostream>2usingnamespacestd;34intx;//Global x56intmain()7{8intx =10;//Local x9cout<<"Value of global x is"<<::x<<...

int aVariable = 3; int someFunction() { int aVariable = 7; print(aVariable); } Depending on the language, this is generally handled in one of three ways: Throw an error for declaring a variable that already exists. Assume the print statement references the local variable. Assume the ...
Nearly every programming language has a concept of local variable. As long as two functions mind their own data, as it were, they won’t interfere with each other. That’s definitely a factor in the previous example (Example 4.2). Both main and prime have a local variable named i. If...
