형변환 함수
#include <stdlib.h>
문자열을 숫자로 변환
int atoi(char *source_buffer)
long atol(char *source_buffer)
float atof(char *source_buffer)
숫자를 문자열로 변환
char *itoa(int value, char *string, int radix)
char *ltoa(long value, char *string, int radix)
char *ftoa(float value, char *string, int radix)
실수형 숫자를 문자열로 변환

sccanf
scanf처럼 키보드 입력을 받지 않고, 문자열에서 데이터를 추출 한다.
format :
int sscanf(const char* buffer, const char* format, [...address]);
#include <stdio.h>
#include <string.h>
char str[128];
int i,j,k;
strcpy(str, "One = 1, Two = 2, Three = 3");
sscanf(str,"One = %d, Two = %d, Three = %d", &i, &j, &k);
printf("%d, %d, %d \n", i, j, k);
