C program to generate pseudo-random numbers using rand and random function (Turbo C compiler only). Function rand() returns a pseudo-random number between 0 and RAND_MAX. Random numbers can be used for security, lottery, etc. I was wondering if we want to generate a random number between 0 and 100, it means [0,100], so it’s should contain also 100. if so, we should do “rand()%101”, is that right?! Another property of a true random number is that nobody should be able to reconstruct the sequence at a later time. Also, create two more variables to use in the for loop. These cookies will be stored in your browser only with your consent. If you want the latter, you would have to say, add 1.0 to RAND_MAX in the divisor. The Base module currently provides an implementation for the types Float16, Float32, and Float64 (the default), and their Complex counterparts. To generate a random number between 1 and 100, do the same, but with 100 in the second field of the picker.
