Answer:
Join
Explanation:
Five basic set operators in relational algebra are as follows:
- Selection - tuple selection
- Projection - extract columns
- Cartesian product - cross product of relations
- Set union - union of two relations
- Set difference - minus operation on two relations
As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.
Answer:
#include <iostream>
#include <cstring>
using namespace std;
void replacePeriod(char* phrase) {
int i = 0;
while(*(phrase + i) != '\0')
{
if(*(phrase + i) == '.')
*(phrase + i) = '!';
i++;
}
}
int main() {
const int STRING_SIZE = 50;
char sentence[STRING_SIZE];
strcpy(sentence, "Hello. I'm Miley. Nice to meet you.");
replacePeriod(sentence);
cout << "Updated sentence: " << endl;
cout << sentence << endl;
return 0;
}
Explanation:
- Create a function called replacePeriod that takes a pointer of type char as a parameter.
- Loop through the end of phrase, check if phrase has a period and then replace it with a sign of exclamation.
- Inside the main function, define the sentence and pass it as an argument to the replacePeriod function.
- Finally display the updated sentence.
