Write a program to find the number of and sum of all integers greater than 100 and less than 200 that are divisible by 2?

Answer 1

You will need some variables first:

amount - store the amount of "divisible by 7" integers

total - store the sum of these integers

count - a number that will control the while loop (or you can use a for loop an exclude this)

amount = 0, total = 0, and count = 101

A special math operator is also needed, it's called modulus, it's the same as division except instead of dividing a number it finds the remainder. It uses a percent sign %

Modulus (or Mod for short) is important for this type of problem, as it can easily tell us if a number is divisible by 7. If the number Mod 7 equals 0 then it means the number is divisible by 7.

Now the while loop:

while (count < 200) {

if (count % 7 == 0) {

amount++;

total += count;

}

count++;

}

When this loop is done, amount will be the amount of numbers that are divisible by 7, and total will be all of those numbers added together. Simply print those two variables using System.out.println(); and you will have your answer.

If you want to print out each number onto the screen, just insert System.out.printlin(count); into the if statement of the while loop, then every number that's divisible by 7 will be shown on screen.

Answer 2

public static void main(String[] args) { int count = 0; int sum = 0; for(int i = 100; i < 200; i++) { if(i%7 == 0){ System.out.println(i); count++; sum = sum + i; } } System.out.println("Number of values divisble by 7 is: " + count); System.out.println("Sum of the values divisible by 7 is: " + sum); }

Answer 3

int num = 0;

int sum = 0;

// First number greater than 100 that is divisible by 7 is 105.

// To find the next number that is divisible by 7, simply add 7.

for(int n = 105; n < 200; n+=7) {

// Update totals.

++num;

sum += n;

}

Answer 4

...
int sum = 0;
for (int i = 101; i <= 199; i++)
if (i % 7 == 0) sum += i;
...

...
int sum = 0;
for (int i = 101; i <= 199; i++)
if (i % 7 == 0) sum += i;
...

...
int sum = 0;
for (int i = 101; i <= 199; i++)
if (i % 7 == 0) sum += i;
...

...
int sum = 0;
for (int i = 101; i <= 199; i++)
if (i % 7 == 0) sum += i;

Answer 5

cls

rem a program to sum two number

read a,b

data 10,30

sum=a+b

print "the result of sum=";sum

end

Answer 6
