Reference Versus Value

in CS 102 on C++

What is the difference between reference and value? How can we ‘pass by reference’ versus ‘pass by value’?

#include <iostream> 
 
using namespace std; 
 
// CALL BY VALUE is the default way of passing parameters 
// in C/C++: the parameter is a COPY of the original, so 
// the function can't change the original. 
int changeByValue(int x, int amount); 
 
// CALL BY REFERENCE is indicated by the (&) after the type 
// of the parameter. It means the parameter is initialized 
// as a reference (aka a pointer) to the original value,  
// so it can change the original. 
int changeByRef(int& x, int amount); 
 
int main(){   
    int x = 10; 
    changeByValue(x, 23);   
    cout << "x = " << x; 
    changeByRef(x, 23); 
    cout << "x = " << x; 
    return 0; 
} 
 
int changeByValue(int x, int amount) {
    x = x + amount;   
    return x; 
} 
 
int changeByRef(int& x, int amount) {   
    x = x + amount;   
    return x; 
}

Systems Development Life Cycle

in BUS 110

What are the phases of the SDLC and why are they important? Handout: PDF

System development is the process of planning, creating, testing, deploying and maintaining a business information system. The idea of a system applies to any range of hardware (a physical device used in or with your system; e.g., the hard drive of your computer) or software (any intangible device; e.g., computer programs or procedures that perform some task on a computer system).
