};
class ConcreteClass: public AbstractClass {
public:
bool checkUpperCase(string inputString) {

for (int i=0; i < strlen(inputString); i++) {
if (isupper(inputString[i])) {
isUpper = true;
break;
}
return isUpper;
}
string lowerToUppercase(string inputString) {
for (int i=0; i < strlen(inputString); i++) {
putchar(toupper(inputString[i]));
}
return inputString;
}
