# C Program to Generate Random numbers within a Range2 min read

In this tutorial, you will learn to generate random numbers within a range in C programming. But before that, you may go through the topic below if you do not know about the` rand()` and `srand()` function used in random numbers generation.

Here we will use srand() function provided in C to generate random numbers. The current time will be used to seed the srand() function.

## C Program to generate random numbers within the range

Since the rand() will generate random numbers between 0 to max value, but instead of 0 we want to enter the lower range as well as the upper range so here is the trick we need to implement.

`(upRange - lrRange + 1))` then add the lower range at the end.

Output:

`Enter how many random numbers you want: 7 Enter the lower range: 10 Enter the upper range: 50 7 random numbers are: 22 29 24 33 18 41 11`

Again execute the program but this time entered for 10 random numbers, start from 1 and give upper range 7.

`Enter how many random numbers you want: 10 `
`Enter the lower range: 1 `
`Enter the upper range: 7 `

`7 random numbers are: `
`1 3 7 7 5 2 1 5 1 2`

Notice that the program is repeating the number as you requested for 10 random numbers but the range is limited to 7 numbers. Hence the program repeats the number.
