Technical Section

1). What will be the output of the program?

#include

int main()

{

int k, num = 30;

k = (num < 10) ? 100 : 200;

printf("%d\n", num);

return 0;

}

|A.|200 |B.|30 |

| | | |[pic] |

| | | | |

|C.|100 |D.|500 |

Answer: Option B

Explanation:

Step 1: int k, num = 30; here the variable k and num is declared as integer type and num is initialized to 30.

Step 2: k = (num > (num < 10? 100: 200): 500); this statement does not affect the output. Let's skip this step.

Step 3: printf("%d\n", num); It prints the value of variable num.

Hence the output is "30".

2). What will be the output of the program?

#include

int main()

{

int a = 300, b, c;

if(a >= 400)

b = 300;

c = 200;

printf("%d, %d, %d\n", a, b, c);

return 0;

}

|A.|300, 300, 200 |B.|Garbage, 300, 200 |

|C.|300, Garbage, 200 |D.|300, 300, Garbage |

| |[pic] | | |

| | | | |

Answer: Option C

Explanation:

Step 1: int a = 300, b, c; here variable a is initialized to '300', variable b and c are declared, but not initialized.

Step 2: if(a >= 400) means if(300 >= 400). Hence this condition will be failed.

Step 3: c = 200; here variable c is initialized to '200'.

Step 4: printf("%d, %d, %d\n", a, b, c); It prints "300, garbage value, 200". because variable b is not initialized.

3). What will be the output of the program?

#include

int main()

{

int i = 5;

while(i-- >= 0)

printf("%d,", i);

i = 5;

printf("\n");

while(i-- >= 0)

printf("%i,", i);

while(i-- >= 0)

printf("%d,", i);

return 0;

Answer: Option A

5). #include

int main()

{

int a[5] = {5, 1, 15, 20, 25};

int i, j, m;

i = ++a[1];

j = a[1]++;

m = a[i++];

printf("%d, %d, %d", i, j, m);

return 0;

}

|A.|2, 1, 15 |B.|1, 2, 5 |

|C.|3, 2, 15 |D.|2, 3, 20 |

| |[pic] | | |

| | | | |

Answer: Option C

Explanation:

Step 1: int a[5] = {5, 1, 15, 20, 25}; The variable arr is declared as an integer array with a size of 5 and it is initialized to

a[0] = 5, a[1] = 1, a[2] = 15, a[3] = 20, a[4] = 25 .

Step 2: int i, j, m; The variable i,j,m are declared as an integer type.

Step 3: i = ++a[1]; becomes i = ++1; Hence i = 2 and a[1] = 2

Step 4: j = a[1]++; becomes j = 2++; Hence j = 2

Step 5: m = a[i++]; becomes m = a[2]; Hence m = 15 and i is increemented by 1(i++ means 2++ so i=3)

Step 6: printf("%d, %d, %d", i, j, m); It prints the value of the variables i, j, m

Hence the output of the program is 3, 2, 15.

6). What will be the output of the program ?

#include

return 0;

}

|A.|ink |B.|ack |

|C.|ite |D.|let |

Answer: Option A

9). What will be the output of the program?

#include

int main()

{

int x=12, y=7, z;

z = x!=4 || y == 2;

printf("z=%d\n", z);

return 0;

}

|A.|z=0 |B.|z=1 |

| | | |[pic] |

| | | | |

|C.|z=4 |D.|z=2 |

Answer: Option B

Explanation:

Step 1: int x=12, y=7, z; here variable x, y and z are declared as an integer and variable x and y are initialized to 12, 7 respectively.

Step 2: z = x!=4 || y == 2;

becomes z = 12!=4 || 7 == 2;

then z = (condition true) || (condition false); Hence it returns 1. So the value of z=1.
