Thread: Problem starting a homework problem for class. Please help!

This is a sample where you can just read it in as a char string using correct functions. Also it filters out the numbers even if the string also contains some non-numeric characters.

Code:

#include <stdio.h>
int main(){
	char buffer[256];
	fgets(buffer,255,stdin);
	int i;
	for(i=0;buffer[i]!='\0';i++){
		switch(buffer[i]) {
			case '0': printf("zero "); break;
			case '1': printf("one "); break;
			case '2': printf("two "); break;
			case '3': printf("three "); break;
			case '4': printf("four "); break;
			case '5': printf("five "); break;
			case '6': printf("six "); break;
			case '7': printf("seven "); break;
			case '8': printf("eight "); break;
			case '9': printf("nine "); break;
		} 
	}
	fgets(buffer,255,stdin);
}
