Generate random array in C++

By Shubham Chandrakant Shinde

In this C++ project, we will see the random array generation means random values are generated and inserted into the array.

First, you can download the source code and unzip it to use. U can run this source code on any platform like Visual Studio Code, Dev c++, etc.

Program:

rand():

The rand() function will generate random number.

For integer data:
I_elements = rand() % 100; //It generate random number between 0 to 99
For floating data:
F_elements = (rand() / 7.5);

We can't generate floating numbers directly, so we have to divide the rand() function with any floating-point number to generate a random float number.

Label:

Labels are used as targets for the goto statement.

Random: //the label is used instead of loops and switch 

goto Random; //goto keyword is used to jump to a specific label
I_count and F_count variables are used as a counter location for array elements

 

Working of the program-

Input:- 

Need to specify the size of the array as shown below.

p2_out1

select choice for the integer data type.

p2_out2

select choice for the float data type.
