Here is given the corresponding output, for example:
2


#include
#include
using namespace std;
Int main ()

{
[20] char a, b [20].
Int L1, L2, I, j, count=0;
Cin. Getline (a, 20);
Cin. Getline (b, 20);
L1=strlen (a);
L2=strlen (b);


for (i=0; i For (j=0; J & lt; L2; J++)
If (a [I]==b [j])
count++;
Cout & lt; return 0;

}
