Definition

Combining elements end-to-end to form 1 combined result. In the case of computer programming, an element could be a string but the result is always saved to a string.

Explanation

It is a way of making a new string (or sentence), by putting together two or more elements.

How strings can be made:

string a = "abc";
string b = "def";
string c = "123";

int i = 123;
int j = 45;
float k = 6.34f;

string result1 = a + b; // result1 = "abcdef"
string result2 = a + i; // result2 = "abc123"
string result3 = i + a; // result3 = "123abc"
string result4 = c + i; // result4 = "123123"
string result5 = j + k; // result5 = "456.34" because even though both variables are numbers, because we are saving it as a string, it will concatinate instead of actually adding the numbers
string result6 = a + b + i; // result6 = "abcdef123" concatenation can also be with multiple elements, not just two elements

/*
"abc" + "def" = "abcdef"
“abc” + 123 = “abc123”
123 + “abc” = “123abc”
“123” + 123 = “123123”
45 + 6.34f = "456.34"
"abc" + "def" + 123 = "abcdef123"
*/
