c/c++整理--實作删除字元串所有指定字元

程式設計實作删除字元串中所有指定的字元

示例輸入：cabcdefcgchci

示例輸出：abdefghi

#include <stdio.h>
#include <stdlib.h>
#define N 20

char* deleteChar(char* bef, char c);

int main()

	char c, i = 0, j = 0;
	char bef[N] = {0};
	char *aft;
	
	printf("input char: ");
	scanf("%c", &c);
	printf("before delete: ");
	scanf("%s", bef);
	
	aft = deleteChar(bef, c);
	
	printf("after delete: %s\n", aft);
	
	return 0;
}

char* deleteChar(char* bef, char c)
{
	char *aft = (char*)malloc(sizeof(char) * N);
	char *tmp = aft;

	while(*bef)
	{
