Answer 1

7. d) None of the above.

9 #include <stdio.h> 10 11 int main() 12 13 float x (float) 7/3; 11 4 15 print i ("%. 2f",x); 2.33 Program finished with exit code

float x = (float) 7/3; // This line converts the value of 7/3 into float and stores the vlaue in x. i.e., x = 2.333333

printf("%.2f", x); // This line fixes the value of x to 2 decimal points and prints the output. i.e., x = 2.33

The output is 2.33

Therefore the answer is None of the above.

8. b) TRUEFALSE

#include <stdio.h> 10 11 int main() 12- 13 int x 3; if(x 3 ||x 2) printf("TRUE"); printf("FALSE"); 15 17 inp TRUEFALSE ... Program finished with exit code 0 Press ENTER to exit console.

int x = 3; //

if(x > 3 || x !=2) printf("TRUE"); // if the value of x is greater than 3 or if the value of x is not equal to 2 then it prints output TRUE.

printf("FALSE"); // Since this statement is outside the if condition it always get printed.

Hence the output is TRUEFALSE

9. c) TRUETRUETRUE

Output:

9 #include <stdio.h> 10 11 int main() 12- 13 14 switch(x 1)0 15 16 17 18 108 intx 3; case 3: printf("TRUE") case 4: printf("TRUE") default: printf("TRUE") printf("TRUE"); 21 TRUETRUETRUE

SYNTAX OF SWITCH:

switch(x){

case 1:

some statement

break;

case 2:

some statement

break;

case 3:

some statement

break;

default: some statement

}

int x = 3; // variable declaration

switch(x + 1){ // This is a switch statement. Since x =3, switch (x +1) becomes switch(4)

case 3: printf("TRUE"); // if(x = 3) it prints TRUE

case 4: printf("TRUE"); // if(x = 4) it prints TRUE. Since the variable x = 4(after coming into switch condition), case 4 gets printed.

default: printf("TRUE"); // by default if no case is true it prints this statement.

Since there is are no break statements in the switch case, the default statement also gets printed.

}

printf("TRUE"); // Since this statement is outside the switch condition it is printed everytime. This line is also printed.

Hence the output becomes TRUETRUETRUE.
