Been given a task to change my code to dynamic array. The program asks you to input array size 1 to 100. After that input vowels 1 by 1 with the normal array teikums[100]; it outputted the vowels and the vowel amount. Been given a task to make dynamic array without the "new". But after adding the dynamic array:
char *teikums = (char*)malloc(100);
It outputs blank space.
