Run the “hello, world”
To run the hello world program and experiment with leaving out parts of the hello world program, to see the error message.
Explanation of Solution
Program:
//Leaving out header file //#include <stdio.h> main() { printf("Hello, "); printf("World"); printf("\n"); }
Explanation:
The program above leaving the header file <stdio.h> statement to see the error. There is a warning in the program and shows the output.
Sample Output:
Program:
#include <stdio.h> //Leaving out main function //main() { printf("Hello, "); printf("World"); printf("\n"); }
Explanation:
The program above leaving the main function to see the error. There is an error in program line 4.
Sample Output:
Program:
#include <stdio.h> main() { //Leaving out first statement line //printf("Hello, "); printf("World"); printf("\n"); }
Explanation:
The program above leaving the first statement line to see the error. There is no error and print world, then a new line.
Sample Output:
Program:
#include <stdio.h> main() { printf("Hello, "); //Leaving out second statement line //printf("World"); printf("\n"); }
Explanation:
The program above leaving the second statement line to see the error. There is no error and print hello, then a new line.
Sample Output:
Program:
#include <stdio.h> main() { printf("Hello, "); printf("World"); //Leaving out third statement line //printf("\n"); }
Explanation:
The program above leaving the third statement line to see the error. There is no error and print hello,world without a new line.
Sample Output:
Program:
#include <stdio.h> //Leaving out curley braces. main() //{ printf("Hello, "); printf("World"); printf("\n"); //}
Explanation:
On leaving the curly braces the program will not compile and produce compilation error.

- Why am I getting an error? What do I change to make it work?arrow_forwardCould you please with writing this code? Thank you.arrow_forwardSo the histogram isn't showing in my program when I type 0, it just says invalid input and continues on with the code. I see it works on your side, but I need it to stop the code completely and show the stars for the numbers inputed.arrow_forward

Thank youarrow_forwardProgramming Exercise Numeric Triangle Pattern Based on the example given on the previous module, create a program that replicated the triangle pattern shown. Try to look at the examples closely and think of an algorithm that replicates the outputs. Let's see if you still look at Triangle problems the same way after this problem. Input: Integer value n. Output: A triangle based on the inputted value of n. Sample Input and Outputs: Input Output 3 ** *** 4 * ** *** **** 7 * ** *** **** *****arrow_forward
- Please add interrupts to this code. Modify this as it's not using any interrupts in the implementation. Use a button or a sensed condition that trigger the temperature to read, then switch on the LCD and display. Or simply sense and display the new temperature in response to a different input.arrow_forwardwrite a program to enter a user name and display the message (hello) three times. The first one for (Mena), the second one for (Nastia) and the third for any user as a guest. (For example, hello mena, hello Nastia et.al.)arrow_forwardOh, no! In a lengthy text, you mistakenly erased all spaces, punctuation, and capitalization. "I reset the computer," for example. It still didn't boot!" was changed to "iresetthecomputeritstilldidntboot". You may deal with the punctuation and capitalization later; for now, just replace the spaces. The majority of the terms are in dictionaries, but a handful are not. Design a method to unconcatenate the text in a way that reduces the amount of unknown characters given a dictionary (a list of strings) and the document (a string).
