Find the output of the program

#include<stdio.h>

int main()

{

int x;

for(x=-1; x<=10; x++)

{

if(x < 5)

continue;

else

break;

printf(“Alpingi”);

}

return 0;

}

As a project, Parag wants to write a code which should increment its value until a condition is satisfied. Which type of structure should he be using?

Find the output of the program

#include<stdio.h>

int main()

{

int i=1;

for(;;)

{

printf(“%d\n”, i++);

if(i>10)

break;

}

return 0;

}

Integer a = 20, b =10, c = 20, d =10

Print a*b/c-d

Print a*b/(c-d)

Will the output be same for the two ?

What will be the output of the following pseudo-code statements:

integer a = 456, b, c, d =10

b = a/d

c = a – b

print c

What will be the output of the following pseudo-code statements:

integer a = 984, b, c, d =10

print remainder(a,d) // remainder when a is divided by d

a = a/d

print remainder(a,d) // remainder when a is divided by d

A company offers commission for selling it products to its salesperson. The



commission rate is Rs. 5 per product. However if the salesperson sells more than 200



items, he gets a commission of Rs. 10 on all items he sold after the first 200. Kanu



writes a program to calculate the commission for the salesperson:



integer numberProducts, commission



input numberProducts



if ( numberProducts > 200 )



— MISSING STATEMENT —



else



commission = numberProducts * 5



end if



print commission



Fill in the missing statement.

. Vikram wants to write a program which checks whether the inputted number



is divisible by any of the first 6 natural numbers (excluding 1). He writes the following



efficient code for it.



int number, n = 2, isdivisible=0



input number



while ( n <=6) // Statement 1



{



if ( remainder (number, n) == 0)



isdivisible = 1



end



n = n+1 // Statement 2



}



if (isdivisible equals 1)



print “It is divisible”



else



print “It is not divisible”



end



Vikram takes the program to Hari. Hari tells Vikram that though the code is correct, it



can be made more efficient. Hari modifies a single statement and makes the code



more efficient. Which statement does he modify and how?

 I have a problem to solve which takes as input a number n. The problem has a



prAnswererty that given the solution for (n-1), I can easily solve the problem for n. Which



programming technique will I use to solve such a problem?
