10. Code of character - solution

---

First, a random number is generated using the rand () function.
the srand (time (0)) function returns the largest value that the next rand () function will generate. And it is also a random number obtained by the function time (0). In order to use the mentioned functions, it is necessary to include files:
#Include <stdlib.h>
#include <time.h> / * time * /

​

Tby dividing the remainder by 150, it limits this number from 0-149
To generate a random number from 1 to 150 you need to write
​codeOfCharacter =1+ rand()%150
Using further if-else if-else if-else determines which case of the offered 4
When printing the character code, as well as the character itself, an integer code is used in both cases, but for the format, in the case of an integer, "% d" is used, while "% c" is used to display the character. For example
printf("Capital letter %d %c\n",codeOfCharacter ,codeOfCharacter );
