Question

Answer the following questions by creating a ten-bit binary number, abcdefghij, such that a digit is 1 if corresponding question is true, and 0 is it is false. Write a small C function that converts the particular binary number you found to hexadecimal. Each correct digit is worth 1 point.

a) Any C program has to return a zero when it exits if the entry point in a C program is in this

particular format : int main(int* argc, char** argv)

b) A syntax error in a C program is an error that causes the program to produce incorrect output(s),

or crash.

c) If you declare this : int single = 1, double = 2, triple = 3; in your code, it compiles fine.

d) After the last statement of any declared C function executes, such as its return statement,

control is transferred to the next defined function.

e) The symbol = is the C equality operator.

f) If you write while(0){} in your program, leaving the brackets empty, your program will stop at

that point and never exit the loop.

g) If integer z is 6, after this C statement executed z will not be incremented : if(z=5) z++;

h) A type double variable represents same range of values than can be represented by a type int

variable.

i) Given this prototype of a C function, void one(int x, double y); and assuming that the <math.h>

library header file were #included, and PI is #defined as 3.14, this following call would cause an

error : printf(

Explanation / Answer

Answer the following questions by creating a ten-bit binary number, abcdefghij, such that a digit is 1
if corresponding question is true, and 0 is it is false. Write a small C function that converts the particular binary number you found
to hexadecimal. Each correct digit is worth 1 point.

string to_hexadecimal(string binary)
{
int sum =0;
for(int i=binary.length()-1; i>=0; i++)
sum = sum + (binary[i]-'0')*pow(2,i);
char* table = "0123456789ABCDEF";
string str="";
while(sum)
{
str = table[sum%16]+str;
sum = sum/16;
}
}

a) Any C program has to return a zero when it exits if the entry point in a C program is in this
particular format : int main(int* argc, char** argv)

True

b) A syntax error in a C program is an error that causes the program to produce incorrect output(s),
or crash.

False;

c) If you declare this :
int single = 1, double = 2, triple = 3; in your code, it compiles fine.

False   double is data type not a variable.

d) After the last statement of any declared C function executes, such as its return statement,
control is transferred to the next defined function.

False.. control transferred back to function where it is called.

e) The symbol = is the C equality operator.

False == is equality operator.

f) If you write while(0){} in your program, leaving the brackets empty, your program will stop at
that point and never exit the loop.

False... that code never executes

g) If integer z is 6, after this C statement executed z will not be incremented : if(z=5) z++;

False.   since z=5 is not equality statement.. z will be incremented.

h) A type double variable represents same range of values than can be represented by a type int
variable.

True.

i) Given this prototype of a C function, void one(int x, double y); and assuming that the <math.h>
library header file were #included, and PI is #defined as 3.14, this following call would cause an
error : printf(
