Write a program to test the difference between %d and %i conversion

1 answer:

7 0

Void test(char *s)
{
int i, d;
sscanf(s, "%i", &i);
printf("%s converts to %i using %%i\n", s, i);
sscanf(s, "%d", &d);
printf("%s converts to %d using %%d\n", s, d);
}

int main()
{
test("123");
test("0x123");
return 0;
}

outputs:
123 converts to 123 using %i
123 converts to 123 using %d
0x123 converts to 291 using %i
0x123 converts to 0 using %d

As you can see, %i is capable of parsing hexadecimal, whereas %d is not. For printf they're the same.

Set numMatches to the number of elements in userValues (having NUM_VALS elements) that equal matchValue. Ex: If matchValue = 2 a

xenn [34]

Answer:

import java.util.Scanner;

public class FindMatchValue {

public static void main (String [] args) {

final int NUM_VALS = 4;

int[] userValues = new int[NUM_VALS];

int i = 0;

int matchValue = 0;

int numMatches = -99; // Assign numMatches with 0 before your for loop

userValues[0] = 2;

userValues[1] = 2;

userValues[2] = 1;

userValues[3] = 2;

matchValue = 2;

numMatches=0;

for(i=0;i<NUM_VALS;i++)

{

if(userValues[i]==matchValue)//cheking if the array element is equal to match value.

{

numMatches++;

}

System.out.println(numMatches);//printing the matchvalue.

}

Output:-

Explanation:

First I have set the value numMatches to 0 before the loop.Then I have user the for loop to iterate over the array.In the for loop I am checking that the array element is equal to the matchValue or not if it is equal then increasing the numMatches by 1.Then at last print the value of numMatches.

Phoebe has to give a presentation about recycling. Where should she look while presenting?

Naddika [18.5K]

Well, I think that maybe the answer is B or C. She shouldn't only look at her presentation while she is presenting it, that doesn't look professional, and you want to look at the people you are talking to.

Integers and booleans. Write a program RightTriangle that takes three int command-line arguments and determines whether they con

icang [17]

Answer:

The programming language is not stated;

I'll answer using C++

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int side1, side2, side3;

cout<<"Enter the three sides of the triangle: "<<endl;

cin>>side1>>side2>>side3;

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

else {

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

else {

cout<<"Not Right Angled";

}

return 0;

}

Explanation:

The following line declares the three variables

int side1, side2, side3;

The next line prompts user for input of the three sides

cout<<"Enter the three sides of the triangle: "<<endl;

The next line gets user input

cin>>side1>>side2>>side3;

The following if condition checks if any of user input is negative or 0

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

If otherwise

else {

The following if condition assumes that side1 is the largest and test using Pythagoras Theorem

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side2 is the largest and test using Pythagoras Theorem

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side3 is the largest and test using Pythagoras Theorem

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

If none of the above conditions is true, then the triangle is not a right angles triangle

else {

cout<<"Not Right Angled";

}

}

return 0;

I don’t really understand what this question is asking 100%, but you can either walk into the McDonald’s you want to work at and ask for an application. They might give it to you, but will most likely tell you to apply online.

If they do tell you to apply online, go to the McDonald’s website and scroll all the way down to the bottom.

There are sections you can choose such as: About Us, Careers, Services, Community, and Contact Us.

Clearly you want to go to Careers.

Under Careers are: Education Opportunities, Employee Perks, Meet Our People, Working With Us, and Apply Now.
