Code: #include void reverseSentence(); int main() { printf("Enter a sentence: "); reverseSentence(); return 0; } void reverseSentence() { char c; scanf("%c", &c); if (c != '\n') { reverseSentence(); printf("%c", c); } }
It is a predefine of a function that will be defined later somewhere. However, #include at the beginning of a line is wrong.
