关于数组指针的c++程序，不知道为什么错了

Question

#include
#include
using namespace std;
int main(){
char str1[80], str2[80];
char pc1 = str1, *pc2 = str2;
cin >> pc1 >> pc2;
char a[80][80];
for (unsigned i = 0; i<strlen(str1) - strlen(str2) + 1; i++){
for (unsigned j = 0; j<strlen(str2); j++)
a[i][j] = *(pc1 + i + j);
}
char(*pa)[80];
pa = a;
for (unsigned i = 0; i<strlen(str1) - strlen(str2) + 1; i++){
if (strcmp((pa + i), str2) == 0)
cout << str1[i];

}

}
