write c++ statements to declare an integer variable score and a double constant TARGET. initialize them with 15 and 20.0 respectively?

Given a string, an integer position, and a character, all on separate lines, find the character of the string in that position and replace it with the character read. Then, output the result.

Ex: If the input is:

warn

e

the output is:

earn

Note: Using a pre-defined string function, the solution can be just one line of code.

#include <iostream>

#include <string>

using namespace std;

int main() {

  string stringVal;

  int stringPos;

  char substituteChar;

  getline(cin, stringVal);

  cin >> stringPos;

  cin >> substituteChar;

  cout << stringVal << endl;

  return 0;

}

4. Write a C++ program that

1) prompts the user to input 3 decimal numbers (with a fraction part)

2) Prints the three decimal numbers.

3) Converts each decimal number to the nearest integer.

4) Prints the three converted numbers.

What is printed by the following code?

#include <iostream>

#include <math.h>

using namespace std;

int main(int argc, const char * argv[]) {

  // insert code here...

  double Num1, Num2;

  cout << "Please enter two float number : ";

  cin >> Num1 >> Num2;

  double average = (Num1 + Num2)/2;

  cout << "The average between these number is :m" <<average << endl;

  cout << "The nearest integer around the average is : " << round(average)<<endl;

  return 0;

>=70% grade A

Between 60 and 70% grade B

Between 50 and 60% grade C

Between 40 and 50% grade D

Below 40% grade E
