C语言练习题 如何在二维数组中查找元素

已知表示颜色的单词在2维数组中：
char color[][20]={"amber","chartreuse","antique","cornsilk"," white","navy","violet","azure","black","pink","scarlet","blue","coral","brown","yellow","orchid","cyan","mauve","orange","pansyrubine" };
输入一个颜色，查找是否在color中，如是，输出在color中的下标，否则输出-1

Answer 1

#include <stdio.h>
extern int strcmp(const char *, const char *);

int main()
{
	int index = -1;
	int i;
	char color[][20]={"amber","chartreuse","antique",
		"cornsilk","white","navy","violet","azure",
		"black","pink","scarlet","blue","coral",
		"brown","yellow","orchid","cyan","mauve",
		"orange","pansyrubine"};
	char find[20];
	printf("Please input a string...\n");
	gets(find);
	for(i=0;i<20;i++){
		if(strcmp(color[i],find)==0){
			index = i;
		}
	}
	printf("index : %d\n",index);
	return 0;
}
