# Generating random number in a range in C

How to generate a random number in a given range in C.

Examples:

```Input : Lower = 50,
Upper = 100,
Count of random Number = 5
Output : 91 34 21 88 29
Explanation: lower is the lower limit of the
range and upper is the upper limit of the range.
Output contains 5 random numbers in given range.

```

As C does not have an inbuilt function for generating a number in the range, but it does have rand function which generate a random number from 0 to RAND_MAX. With the help of rand () a number in range can be generated as num = (rand() % (upper – lower + 1)) + lower

 `// C program for generating a ` `// random number in a given range. ` `#include ` `#include ` `#include ` ` `  `// Generates and prints 'count' random ` `// numbers in range [lower, upper]. ` `void` `printRandoms(``int` `lower, ``int` `upper,  ` `                             ``int` `count) ` `{ ` `    ``int` `i; ` `    ``for` `(i = 0; i < count; i++) { ` `        ``int` `num = (``rand``() % ` `           ``(upper - lower + 1)) + lower; ` `        ``printf``(``"%d "``, num); ` `    ``} ` `} ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``int` `lower = 5, upper = 7, count = 1; ` ` `  `    ``// Use current time as  ` `    ``// seed for random generator ` `    ``srand``(``time``(0)); ` ` `  `    ``printRandoms(lower, upper, count); ` ` `  `    ``return` `0; ` `} `

Output:

```7
```

Note : Output generated on each run may be different because number is generated randomly.
