problem1)

a)

prepare a C program that shows the use of mathematical functions to compute

i) absolute value of a real number

ii) exponential of a real number

b) prepare C statements which show the use of escape sequences\ n and\?

c) Describe how variables of type int , long int , short int and unsigned int are declared.

d) Which of the following are valid C variables?

i) Count_xyz

ii) Continue

iii) const

iv) case

v) enum_variable

problem2)

a) The program given below shows how char and int data types could be used interchangeably.

Find the output of the program.
#include

int
main()
{
char
height=72,width=87,length=76;
int
volume;
printf("The formula for volume is\n");
printf(“%c=%c*%c*%c”,’V’,height,width,length);
volume = height*width*length;
printf(“\nvolume=%d”,volume);
return0;
}

b) Identify the syntax errors in the following statements, if any, and do the essential corrections. (Suppose that x, y, z are declared as int variables.)

i) scan f(“%d,%d”, x,y);

ii) if (x =! y) z = x-y, y = z + x;

iii) print f(“%d,z = ” &z);

iv) x = x + y =< 30;

c) Describe step by step the statement result += (value++ * 5) + ( value++ *3);

d) Describe the output of the following piece of the code

if(!((7>5)*(6<5)))

{printf("Go to your home.");
goto Home;}

else printf("Come,let's study together");

Home: printf(“\n Bye..See you Tomorrow!”);
