The first 11 prime integers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. A positive integer between 1 and 1000 (inclusive), other than the first 11 prime integers, is prime if it is not divisible by 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. Write a program that: Prompts the user to enter a positive integer between 1 and 1000 (inclusive) Outputs whether the number is prime. If the number is not prime, then output all the numbers, from the list of the first 11 prime integers, which divide the number. In C also the output should look like this Enter an integer between 1 and 1000 (inclusive): 62 62 is divisible by 2, 31. 62 is not prime. ---------------------------------------------------- Enter an integer between 1 and 1000 (inclusive): -1 You must enter a number between 1 and 1000 (inclusive). ---------------------------------------------------- Enter an integer between 1 and 1000 (inclusive): 3 3 is prime.
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
- The first 11 prime integers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31.
- A positive integer between 1 and 1000 (inclusive), other than the first 11 prime integers, is prime if it is not divisible by 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31.
Write a program that:
- Prompts the user to enter a positive integer between 1 and 1000 (inclusive)
- Outputs whether the number is prime.
- If the number is not prime, then output all the numbers, from the list of the first 11 prime integers, which divide the number.
In C
also the output should look like this
Enter an integer between 1 and 1000 (inclusive): 62
62 is divisible by 2, 31.
62 is not prime.
----------------------------------------------------
Enter an integer between 1 and 1000 (inclusive): -1
You must enter a number between 1 and 1000 (inclusive).
----------------------------------------------------
Enter an integer between 1 and 1000 (inclusive): 3
3 is prime.
