How do you input only positive numbers in C?

Example

1. Input. array size = 5. Elements = { 10, 2, -1, -6, 30}
2. Output.
3. Input. array size = 4. Elements = {12, -1, 0, 8}
4. Output. Let’s approach the problem in two steps. Get the array elements and print it. Next step we will print only positive elements. Get the array elements and print it. Example.

How do you check if a float is an integer C?

Follow the steps below to solve the problem:

1. Initialize a variable, say X, to store the integer value of N.
2. Convert the value float value of N to integer and store it in X.
3. Finally, check if (N – X) > 0 or not. If found to be true, then print “NO”.
4. Otherwise, print “YES”.

How do you find the positive number in an array?

To find out positive numbers from array: we check each number, if number is greater than or equal to zero then it will be a positive number. We traverse array of integer, if it is positive number then we will print that number of console.

3. Ask the user to enter the total number of the array.
4. Create one integer array.

How to find positive or negative number in C program?

If the number is greater than 0, then the given number is positive, and if it is less than 0, then it is a negative number. If the number is equal to 0, then the given number is 0. C program to find Positive or Negative Number using Nested If Condition

How to check for positive and negative in a switch statement?

First we will check for positive. Use expression to check positive in outer switch. Use switch (num > 0). The above switch expression with either return 1 or 0. Hence for case 1: print positive number. For case 0: write one more nested switch statement with expression to check negative number. Say switch (num < 0).
