Need help understanding each step of the following code. This is the prompt: In c programming capitalize the first occurrence of each vowel (a,e,i,o,u) . For example apple = ApplE; I also want to understand how to start an assignment like this in the future. #include #include #include // Return a newly allocated copy of original // with the first occurrence of each vowel capitalized char* CapVowels(char* original) { int a = 1, e = 1, i = 1, o = 1, u = 1; int count = 0; char c; while (original[count]) ++count; char* modified = (char *) malloc(sizeof(char) * (1+count)); for (int j=0; j
