Code:

```#include <stdlib.h> #include <stdio.h> #include <time.h> inline int rand_mid(int low, int high) {     return (rand() * (high - low)) / RAND_MAX + low; } int main(void) {     int x;     srand(time(NULL));         x = rand_mid(5, 10);     printf("A random number from 5 to 10: %d\n", x);     return 0; }```

Code:

```#include <stdlib.h> //for rand, srand, and RAND_MAX #include <stdio.h>  //for printf and you already know this ;p #include <time.h>  //for time to seed rand /*This function is declared as inline, meaning it is treated as a **macro instead of a function...this causes less overhead */ inline int rand_mid(int low, int high) {     /*take low out of high (subtract), then multiply the result     **by a random number. Divide that result by the constant     **RAND_MAX from stdlib and add low to that. The result is     **a pseudo-random number within the bounds of low and high     */     return (rand() * (high - low)) / RAND_MAX + low; } int main(void) {     int x;     /*seed rand, this is done so that you don't get the same     **set of random numbers every time you run the program     **so you set the seed to the current time, which creates     **pretty good random numbers.     */     srand(time(NULL));     /*pass 5 and 10 as low and high to rand_mid, then     **assign the value returned to x and print it out     */        x = rand_mid(5, 10);     printf("A random number from 5 to 10: %d\n", x);     return 0; }```
