软件里面可以用 交题说不认识这个东西 gets(a);

foo.cc: In function 'int main()':
foo.cc:6:9: error: 'gets' was not declared in this scope; did you mean 'getw'?
    6 |         gets(a);
      |         ^~~~
      |         getw

#include
using namespace std;
char a[1000];
int main()
{
	gets(a);
	char q,w;
	cin>>q>>w;
	int i=0;
	while(a[i]!='\0')
	{
		if(a[i]==q)
		a[i]=w;
		i++;
	}
	cout<<a;
	return 0;
}
