蓝桥杯 基础练习（查找整数）
坑点
记得若不存在，就要输出-1
# include<stdio.h>
int main()
{
int n;
scanf("%d", &n);
int a[n];
int i, obj, ret;
for (i=0; i<n; i++)
{
scanf("%d", &a[i]);
}
scanf("%d", &obj);
ret = -1;
for(i=0; i<n; i++){
if(a[i] == obj){
printf("%d",i+1);
ret = 0;
break;
}
}
if(ret == -1){
printf("-1");
}
return 0;
}
