Programming
Question 1
Consider the following program. Fill in the blanks as per the instructions given below:
• Fill in the blank at LINE-1 and LINE-2 with appropriate statements for class template specialization.
• Fill in the blank at LINE-3 with appropriate initializer list.
The program must satisfy the given test cases.
Solution:
template<>
class Manipulator<const char*> {
char* val;
public:
Manipulator(const char* _val = 0) : val(strdup(_val)) { }
char* deduct(int d){
char* buf = (char*)malloc(strlen(val) - d + 1);
int i;
for(i = 0; i < strlen(val) - d; i++)
buf[i] = val[i];
buf[i] = '\0';
return buf;
}
