Show Array Values in Reverse Order C++ (.cpp)
“How to Show Array Values in Reverse Order C++ (.cpp)” is the today topic of discussion in this tutorial.
What is reverse order?
Suppose, the user enters the numbers as follows;
Entered numbers: 4, 2, 9, 1
In this case, the reverse order will be looks like;
Reverse Numbers: 9, 4, 2, 1
Now, Let’s see the program.
Show Array Values in Reverse Order in C++ using Arrays
In this example, we have created the two arrays;
int array1[100];
int reverse[100];

Show Array Values in Reverse Order in C++ using User Define Functions
In this example, we have created the user defines a function. The user define function is declared, defined and call as mentioned below;
Function Declaration: int fun(int, int[], int[]);
Function Definition:
int fun(int size, int array1[100], int ReverseNumbers[100])
{for(int i=size-1, num=0; i>=0; i–, num++)
{
ReverseNumbers[i]=array1[num];
}}
Function Calling: fun(size,array1,ReverseNumbers);
Let’s see the “Show Array Values in Reverse Order in C++ using user define functions”.
