Question

In C language

5. What is the OUTPUT of each of these programs? If you aren't confident of an answer, type mpile and run the program to test it. (a) <stdio.h> #include int main main int count; int sum0; for (count 1; count10; count++) sum sum+ count; for count printf("sum= %d\n", return 0; sum); )main (b) #include int main ) <stdio.h> main/ int count; int sum -0 for (count 1 count10; count 2) sum sum + count; for count print f ( "sum" %d\n", return 0; sum); main/ (c) <stdio.h> #include int main ) main int count; int product 1; for (count1; count<15; count + 5) product-product count; for count printf("product return 0 main / %d\n", product);

Answer 1

5) a)

Output: 25

Explanation: Here the program is doing the summation of all the numbers from 1 to 10

We have for loop from count = 1 to count = 10 and with everytime count increasing as count = count + 2

So the loop will iterate for i = 1,3,5,7,9

i = 1

sum = sum + count

sum = 0+ 1;

sum = 1

i=3

sum = sum + count

sum = 1+ 3;

sum = 4

.....

similarly it will go till count =9

and we get sum = 25.

5) b)

Output: 66

Explanation: Here the program is doing the summation of all the numbers from 1 to 15

We have for loop from 1 to 15 and with counter increasing as count = count +5 so the loop will iterate for i =1, 6, 11

i = 1

product = product * count

product = 1*1;

product = 1

i=6

product = product * count

product = 1*6;

product = 11

product = product * count

product = 6*11;

product = 66

and we get product = 66.
