The c+ + program is shown below.

#include

using namespace std;

int main () {

cout<<"Numbers less than 1000 which are divisible by 7"<
for (int k=1; k<1000; k++)

{

/ / number should give remainder 0 which show complete divisibility

if (k%7 = = 0)

cout<
}

cout<
for (int k=1; k<1000; k++)

{

if (k%11 = = 0)

cout<
}

cout<
for (int k=1; k<1000; k++)

{

/ / for 11, number should not give remainder 0 which shows incomplete divisibility

if (k%7 = = 0 && k%11! = 0)

cout<
}

cout<
for (int k=1; k<1000; k++)

{

if (k%7 = = 0 && k%11 = = 0)

cout<
}

cout<
for (int k=1; k<1000; k++)

{

if (k%7! = 0 && k%11! = 0)

cout<
}

return 0;

}

Explanation:

The test for divisibility is done by using the modulus operator which is used as a condition inside the if statement. This test is done inside for loop.

All the numbers from 1 to 999, less than 1000, are divided by 7 and / or 11 depending on the sub question. Only the numbers which are completely divisible are displayed. Divisible numbers give remainder 0 always.

The divisibility test by 7 is shown below.

cout<<"Numbers less than 1000 divisible by 7"<
for (int k=1; k<1000; k++)

{

if (k%7 = = 0)

cout<
}

In other words, all the numbers divisible by 7 are same as the numbers in the table of 7.

The same logic shown above is applied for other sub questions to test for divisibility by 11 and combination of 7 and 11.

To improve readability, tabs and new lines are inserted at appropriate places.
