Write a function called upperLower that inputs a line of text into char array s[100]. Output the line in uppercase letters and in lowercase letters This is what I have so far:
void * upperLower (const char * s) {
char *word[sizeof(s)];
for(int i = 0; i < sizeof(s); i++){
*word[i] = s[i];
}
word = strtok(word, " ");
int counter = 0;
while(word != NULL){
if(counter % 2 == 0){
word[counter] = toupper(word);
printf("%s ", word);
}
else{
word[counter] = tolower(word);
printf("%s ", word);
}
counter++;
word = strtok(NULL, " ");
}
}
The method cannot be changed. Must use void * upperLower (const char * s) {
The output should be like THIS is A test
