The safest way is to capture the input as a string and then convert the string to an integer. The reason is that all standard input (regardless of where it comes from) is done through character streams and it's safer to capture this input using a string rather than trying to perform conversions on the incoming data directly.

Output a prompt.Either:Read from standard input (std::cin) to an integer.Or:Read a line from standard input (std::getline()) to a string.Create a string stream (std::stringstream) to read the string.Read from the string stream to an integer.For each integer from 2 to half the entered integer:If the entered integer is divisible by the current integer:The number is not prime.Exit the program.The number is prime.Exit the program.
How would i write a program that takes an integer as an input and reverses its digits as an output?
In java you can do it like this: import java.util.Scanner; public class Sample { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Input an integer: "); int i = input.nextInt(); System.out.print("reverse:"); while(i != 0) { System.out.print(i % 10); i = i / 10; } } }

This is not a perfect program, but it will get you started in the right direction. Works for any INTEGER up to "some" power of 2 (decimals kill the program). PROGRAM binary IMPLICIT NONE INTEGER remainder, quotient, n, int_input, answer REAL input, dec_input WRITE(*,*) 'Input a number to convert to binary' READ(*,*) input int_input = input dec_input = input - int_input dec_input = abs(dec_input) quotient = abs(input) DO WHILE (dec_input==0) n = 0 answer = 0 DO WHILE (quotient>1) remainder = mod(quotient,2) quotient = quotient/2 answer = answer+remainder*10.**n n = n+1 END DO IF (input<0) answer = -answer answer = answer + quotient*10.**n WRITE(*,"(a,i31)") 'Your answer in binary is:',answer END DO END PROGRAM binary

How do you write a program that accepts 50 integer values and sort them in basic programming?
Create an array with 50 elements and input the integers one a time, filling the array. Use an insertion sort on the array for each input except the first. Alternatively, input the values first and then use insertion sort.
How to write a java program to extract the last digit from the input?
Assuming you've entered a multi-digit number whole number (an integer), then take the modus (%) of the number and 10. E.g., if the number input was 1234, then 1234 % 10 is 4. Thus the final digit is 4. Note that modus 10 is the same as dividing the number by 10 and taking the remainder.
