Parallel arrays: Arrays are used to group related data types together. The elements in two arrays with different variables that are related to their position are known as parallel arrays. Establishing relationship between two parallel arrays: Consider two arrays named “strMonth []” and “intBonus []” arrays are declared as follows: string strMonth[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"}; int intBonus[] = {25000, 26000, 27000, 29000, 31000, 34000, 36000, 37000, 38000, 40000, 41000, 45000}; Based on the above example, the relationship is established by using the same subscript for both the arrays. “strMonth[index]” have relationship on “intBonus[index]”. That is, the bonus amount of January month is 25000, February month is 26000, and so on.

Program Plan Intro

Parallel arrays:

Arrays are used to group related data types together. The elements in two arrays with different variables that are related to their position are known as parallel arrays.

Establishing relationship between two parallel arrays:

Consider two arrays named “strMonth []” and “intBonus []” arrays are declared as follows:

string strMonth[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

int intBonus[] = {25000, 26000, 27000, 29000, 31000, 34000, 36000, 37000, 38000, 40000, 41000, 45000};

Based on the above example, the relationship is established by using the same subscript for both the arrays. “strMonth[index]” have relationship on “intBonus[index]”. That is, the bonus amount of January month is 25000, February month is 26000, and so on.
