Answer:
// name of the package
package stringlength;
// Scanner is imported but it is not needed
// So it is commented
// import java.util.Scanner;
// The class name StringLength is defined
public class StringLength {
// main method to signify the beginning of program execution
public static void main(String[] args) {
// if-statement to check if argument is supplied to
// command line
if(args.length > -1) {
// the first argument is read and assigned to input
String input = args[0];
int length = input.length(); // using length() method in String class
System.out.println("Your string has a length of "+length+" characters.");
} else {
System.out.println("Please enter your string argument in quote");
}
}
}
Explanation:
The code works fine with little modification and comments. The user should supply the string arguments in quote. The quote must surround the strings because our logic read the first argument passed to the command line. Inserting a string with space between them will provide a wrong output.

Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int c= 0;//defining integer variable to count number of solutions
int x,y,z;//defining integer variable which is used in the loop
for (x = 0; x <= 100; x++)//defining for loop to x value
for (y = 0; y <= 100; y++)//defining for loop to y value
for (z = 0; z <= 100; z++)//defining for loop to z value
if (4 * x + 3 * y - 9 * z == 5)//use if to check given condition
{
c++;//increment count value
cout << "(" << x << "," << y << "," << z << ")";//print solutions
cout << (c % 11? " " : "\n");//use for add file solution in a row
}
cout << "\n\nThere are " << c << " solution(s)\n";//print solution couts
return 0;
}
Output:
Please find the attached file.
Explanation:
In the above-given code four integer variable "x,y,z, and c" is declared, in which "x,y, and z" is used in the for loop with the if conditional statement that checks the given condition and prints the solution and the "c" variable is used to counts the number of solution, and at the last, it uses the print method to print its values.
