**Question 21**

What will be the output of the program ?

#include

int main()

{

char p[] = "%d\n";

p[1] = 'c';

printf(p, 65);

return 0;

}

What will be the output of the program ?

#include

int main()

{

char p[] = "%d\n";

p[1] = 'c';

printf(p, 65);

return 0;

}

A. A

B. a

C. c

D. 65

Ans. A

Explanation:

Step 1: char p[] = "%d\n"; The variable p is declared as an array of characters and initialized with string "%d" Step 2: p[1] = 'c'; Here, we overwrite the second element of array p by 'c'. So array p becomes "%c". Step 3: printf(p, 65); becomes printf("%c", 65); Therefore it prints the ASCII value of 65. The output is 'A'.

**Question 22**

What will be the output of the program ?

#include

#include

printf("%s\n", strcpy(str2, strcat(str1, str2)));

return 0;

}

A. Hello

B. World

C. Hello World

D. WorldHello

Ans. C

Explanation:

Step 1: char str1[20] = "Hello", str2[20] = " World"; The variable str1and str2 is declared as an array of characters and initialized with value "Hello" and " World" respectively. Step 2: printf("%s\n", strcpy(str2, strcat(str1, str2))); => strcat(str1, str2)) it append the string str2 to str1. The result will be stored in str1. Therefore str1 contains "Hello World". => strcpy(str2, "Hello World") it copies the "Hello World" to the variablestr2. Hence it prints "Hello World".

**Question 23**

Point out the error in the program

SI(p, n, r);

SI(1500, 2, 2.5);

return 0;

}

A. 26250.00 7500.00

B. Nothing will print

C. Error: Multiple declaration of si

D. Garbage values

Ans. C

Explanation:

The macro #define SI(p, n, r) float si; si=p*n*r/100; contains the error. To remove this error, we have to modify this macro to #define SI(p,n,r) p*n*r/100

**Question 25**

What will be the output of the program?

C. 2.250000e+000, 2.250000, 2.25, 2.250000

D. error

Ans. C

Explanation:

printf("%e,", d); Here '%e' specifies the "Scientific Notation" format. So, it prints the 2.25 as 2.250000e+000. printf("%f,", d); Here '%f' specifies the "Decimal Floating Point" format. So, it prints the 2.25 as 2.250000. printf("%g,", d); Here '%g' "Use the shorter of %e or %f". So, it prints the 2.25 as 2.25. printf("%lf,", d); Here '%lf' specifies the "Long Double" format. So, it prints the 2.25 as 2.250000.

**Question 26**

What will be the output of the program?

#include

#include

int main()

{

float n=1.54;

printf("%f, %f\n", ceil(n), floor(n));

C. 1.550000, 2.000000

D. 1.000000, 2.000000

Ans. A

Explanation:

ceil(x) round up the given value. It finds the smallest integer not < x. floor(x) round down the given value. It finds the smallest integer not > x. printf("%f, %f\n", ceil(n), floor(n)); In this line ceil(1.54) round up the 1.54 to 2 and floor(1.54) round down the 1.54 to 1. In the printf("%f, %f\n", ceil(n), floor(n)); statement, the format specifier "%f %f" tells output to be float value. Hence it prints 2.000000 and 1.000000.

**Question 27**

What will be the output of the program?

#include

int main()

{

float a=0.7;

if(a < 0.7f)

printf("C\n");

else

printf("C++\n");

return 0;

}

What will be the output of the program?

#include

int main()

{

float a=0.7;

if(a < 0.7f)

printf("C\n");

else

printf("C++\n");

return 0;

}

A. C

B. C++

C. Compiler error

D. Non of above

Ans. B

Explanation:

if(a < 0.7f) here a is a float variable and 0.7f is a float constant. The float variable a is not less than 0.7f float constant. But both are equal. Hence the ifcondition is failed and it goes to else it prints 'C++'

**Question 28**

A. 4.320000e+01, 43.200001, 43.2

B. 4.3, 43.22, 43.21

C. 4.3e, 43.20f, 43.00

D. Error

Ans. A

Explanation:

printf("%e, ", f); Here '%e' specifies the "Scientific Notation" format. So, it prints the 43.20 as 4.320000e+01. printf("%f, ", f); Here '%f' specifies the "Decimal Floating Point" format. So, it prints the 43.20 as 43.200001. printf("%g, ", f); Here '%g' "Use the shorter of %e or %f". So, it prints the 43.20 as 43.2.
