Why do the query tables use an underscore in their names?

Computers and Technology
1 answer:
Vedmedyk [2.9K]3 years ago

An underscore is a permitted character in documentations such as MySQL. An underscore in query tables can increase readability. For example, if we use thisIsMyColumn as a column name, it is very easy to write. However, this _is_my_column as a column name is more readable.

  System.out.print ("Enter a number between 1 - 30:  ");

  number = input.nextInt();          //input number by the user.

 

 }

 asterisk();           //calling function.

 }

public static void asterisk()          //defination of function.

{

    //body of function.

    int n;                   //local variable.

 for (n= 0; n <= 30; n++)                  //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );                  //print value.

 }

 

  for (n= 0; n <= 30; n++)         //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );     //print value.

 }

 

  for (n= 0; n <= 30; n++)          //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );          //print value.

 }

  for (n= 0; n <= 30; n++)            //using loop for print asterisk

 

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );               //print value.

 }

 

  for (n= 0; n <= 30; n++)             //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );             //print value.

 }

}

}

Output:

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 1  

Enter a number between 1 - 30: 3

Enter a number between 1 - 30: 4

6.10.1: Modify a C string parameter. Complete the function to replace any period by an exclamation point. Ex: "Hello. I'm Miley.
Andrej [43]

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.
