C/C++ support for Visual Studio Code is provided by a Microsoft C/C++ extension to enable cross-platform C and C++ development on Windows, Linux, and macOS.

Nov 05, 2015  Generating random values and numbers is an integral part of computer programming. Randomisation of numbers can be created with the help of the C language. In C, there is a library function called rand which can be used for this process. Apr 09, 2009 C Programming Tutorial - 13 - Seeding Random Numbers thenewboston. Unsubscribe from thenewboston?

Random numbers can be used for security, lottery etc. Random numbers can be used for security, lottery etc. C srand The srand function in C seeds the pseudo random number generator used by the rand function. The seed for rand function is 1 by default. It means that if no srand is called before rand, the rand function behaves as if it was seeded with srand(1).

This way you can get reproduceable sets of numbers - you call srand with a given value and rand then produces a set of values. When you start the program next time and call srand with exact same value rand will produce exactly the same set of values.

If seed is set to 1, the generator is reinitialized to its initial value and produces the same values as before any call to rand or srand. In order to generate random-like numbers, srand is usually initialized to some distinctive runtime value, like the value returned by function time (declared in header ).

Getting started

C/C++ compiler and debugger

The C/C++ extension does not include a C++ compiler or debugger. You will need to install these tools or use those already installed on your computer.

Popular C++ compilers are:

• GCC on Linux
• GCC via Mingw-w64 on Windows
• Microsoft C++ compiler on Windows
• Clang for XCode on macOS

Make sure your compiler executable is in your platform path so the extension can find it. You can check availability of your C++ tools by opening the Integrated Terminal (⌃` (Windows, Linux Ctrl+`)) in VS Code and try running the executable (for example g++ --help).

Install the Microsoft C/C++ extension

1. Open VS Code.
2. Click the Extensions view icon on the Sidebar (⇧⌘X (Windows, Linux Ctrl+Shift+X)).
3. Search for c++.
4. Click Install.

Documentation

You can find more documentation on using the Microsoft C/C++ extension under the C++ section, where you'll find topics on:

Remote Development

VS Code and the C++ extension support Remote Development allowing you to work over SSH on a remote machine or VM, inside a Docker container, or in the Windows Subsystem for Linux (WSL).

To install support for Remote Development:

1. Install the VS Code Remote Development Extension Pack.
2. If the remote source files are hosted in WSL, use the Remote - WSL extension.
3. If you are connecting to a remote machine with SSH, use the Remote - SSH extension.
4. If the remote source files are hosted in a container (for example, Docker), use the Remote - Containers extension.

Feedback

If you run into any issues or have suggestions for the Microsoft C/C++ extension, please file issues and suggestions on GitHub. If you haven't already provided feedback, please take this quick survey to help shape this extension for your needs.

C program to generate pseudo-random numbers using rand and random function (Turbo C compiler only). As the random numbers are generated by an algorithm used in a function they are pseudo-random, this is the reason that word pseudo is used. Function rand() returns a pseudo-random number between 0 and RAND_MAX. RAND_MAX is a constant which is platform dependent and equals the maximum value returned by rand function.

C programming code using rand

We use modulus operator in our program. If you evaluate a % b where a and b are integers then result will always be less than b for any set of values of a and b. For example
For a = 1243 and b = 100
a % b = 1243 % 100 = 43
For a = 99 and b = 100
a % b = 99 % 100 = 99
For a = 1000 and b = 100
a % b = 1000 % 100 = 0

In our program we print pseudo random numbers in range [0, 100]. So we calculate rand() % 100 which will return a number in [0, 99] so we add 1 to get the desired range.

int main(){
int c, n;

printf('Ten random numbers in [1,100]n');

Receive window auto-tuning level enable. for(c =1; c <=10; c++){
n =rand()%100+1;
printf('%dn', n);
}

return0;
}

If you rerun this program, you will get the same set of numbers. To get different numbers every time you can use: srand(unsigned int seed) function; here seed is an unsigned integer. So you will need a different value of seed every time you run the program for that you can use current time which will always be different so you will get a different set of numbers. By default, seed = 1 if you do not use srand function.

C programming code using random function (Turbo C compiler only)

Function randomize is used to initialize random number generator. If you don't use it, then you will get same random numbers each time you run the program.

int main()
{
int n, max, num, c;

printf('Enter the number of random numbers you wantn');
scanf('%d',&n);

printf('Enter the maximum value of random numbern');
scanf('%d',&max);

printf('%d random numbers from 0 to %d are:n', n, max);
randomize();

for(c =1; c <= n; c++)
{
num = random(max);
printf('%dn',num);
}
