rand() and srand() Functions in C

This is a C Program to generate random numbers within given range. This version of code uses rand() and srand() functions. The function srand() is used to initialize the pseudo-random number generator and rand() function generates a pseudo random number.

Here is the source code of the C program to use rand and srand functions. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

```
#include <time.h>
```
```
#include <stdio.h>
```
```
#include <stdlib.h>
```
```
 
```
```
int main(void)
```
```
{
```
```
    int num;
```
```
    /* Seed number for rand() */
```

    srand((unsigned int) time(0) + getpid());

    printf("\nGenerating a random number using srand and rand function.\n");

```
    num = rand();
```
```
 
```
```
    printf("%d\n", num);
```
```
 
```
```
    return EXIT_SUCCESS;
```
```
}
```

$ gcc random.c -o random
$ ./random
