Question

I need to follow the example as shown, Is this missing printf "please enter the ending integer"
Please use this code t follow the assignment and make changes if needed.

#include <stdio.h>

//Define a function that calculates the sum using for loop

int sumFor(int num) {

int sum = 0;

int end = num *2

// Loop through each integer from num to end, adding each value to sum

for(int i = num; i <= end; i++) {

sum += 1;

}

// Return the final sum

return sum;

}

// Define a function that calculates the sum using while loop

int sumWhile(int num) {

int sum = 0;

int end = num * 2;

int i = num;

// Loop through each integer from num to end adding each value to sum

while(i <= end) {

sum += i;

i++;

}

// return the sum

return sum;

}

// Define the main function

int main() {

int daNumba;

// Print welcome message

printf("Welcome to sumTimes2\n\n");

// Print a description of the program

printf("This program will display the prime integers that are in the range between the two integers you enter.");

// Ask the user to enter an integer

printf("Please enter the beginning integer: ");

scanf("%d", &daNumba);

printf("\n");

// If the entered integer is positive, calculate the sum using the given number

if(daNumba > 0){

// Call the sumFor function and print the result

printf("For say the sum is %d\n", sumFor(daNumba));

// Call the sumWhile function and print the result

printf("while says the sum is %d\n", sumWhile(daNumba));

}

// If the entered integer is negative, calculate he sum using the negatice number multiplied by 2

else {

// Call the sumFor function with the negative number multiplied by 2, and print the result

printf("For says the sum is %d\n\n",sumFor(daNumba*));

// Call the sumWhile function with the negative number multiplied by 2, and print the results

printf("While says the num is %d\n\n",sumWhile(daNumba*2));

}

// Print goodbye message

printf("\nThank you for using sumTimes2. Bye!\n");

return 0;

}

CIS158 Programming Assignment - POS
Prime Numbers
Example of Output (user input is in blue)
Welcome to prime Num.
This program will display the prime integers that are in the range
between the two integers you enter.
Please enter the beginning integer: 3
Please enter the ending integer: 15
The prime numbers from 3 to 15 are:
3
5
7
11
13
Thank you for using primeNum. Bye!

Program Name
CIS158 Programming Assignment - POS
Prime Numbers
primeNum
Description
The program will indicate which numbers between the values given by the user are prime.
Requirements
Create the e program primeNum.e in the p05 directory. Using the format and words displayed
in the Example of Output, the program will do the following:
•
Display a the welcome message followed by a blank line
.
• Displays a message that indicates what the program will do followed by a blank line.
•
Asks the user to enter two values that will indicate the range of the search for prime
numbers. See "example output" for the exact wording.
.
• Display the heading "Prime numbers from begin to end are:" Note that begin and
end are the numbers entered by the user.
•
The program will call the function that you will create called primeNum to find out if
the number sent was prime or not. The function primeNum will receive an integer and
if it is prime it will retum 1 and if it is not it will return 0.
.
• If the number is prime, the program will display the number. If it is not prime it will
display nothing.
• A blank line.
.
Ends with a thank you message.
