work sheet on casting...
----------------------------------------
1) Accept two integers and print sum,avg and
difference.
main(){
int n1,n2,sum,diff;
float avg;
printf("\nEnter two integers?");
scanf("%d%d",&n1,&n2);
sum=n1+n2;
printf("\nSum = %d",sum);
avg=(float)(n1+n2)/2; /* explicit casting */
printf("\nAvg = %f",avg);
diff=fabs(n1-n2);
printf("\nDiff = %f",fabs( (double)(n1-n2) ) );
}
2) Accept a floating point value and print only the
dec part
ex: - i/p 10.345 o/p 0.345 only
main(){
float fval , dec;
printf("\nEnter a float val ?");
scanf("%f",&fval);
dec=fval-(int)fval;
printf("\ndec part = %10.3f",dec);
}
3) accept a 4 digit number only
and test the number is
4 digit number or not?
int num;
int
printf("\nEnter A Number ?");
scanf("%d",&n1);
n1>=1000 && n1<=9999 ? printf("\n 4 digit number.."):
printf("\n not a 4 digit number..");
work sheet if /nested if
---------------------------------------------------------------------
1) Swap two variable values with out using 3rd variable
2)Accept two integers and print absolute difference
Hint: diffrence must be +ve (use abs() function )
3) Accept 4 digit year and print leap year or not
4)Accept 3 subject marks of student and print division
>=70% ---- distinction
>=60% ----- first
>=50% ------ pass other wise fail
5) Accept a 4 digit number and print digit sum.
Hint: use operators only
6) Accept a char and print in alternate case
7) Accept 3 integers and print second maximum
8)Accept a floting point value and print only the decimal part
Hint : Example i/p is 10.345 o/p is 0.345
Do in this order : 1 , 2 , 6 , 8 ,3 .....
9)Check Whether a Number is Even or Odd
10)Check Whether a Character is Vowel or consonant
11)Find the Largest Number Among Three Numbers Entered by
User
12) Find all Roots of a Quadratic equation
13)Check Whether the Entered Year is Leap Year or not
14)Check Whether a Number is Positive or Negative or Zero.
15) Checker Whether a Character is an Alphabet or not
16)Find HCF of two Numbers
17)Find LCM of two numbers entered by user
/* work sheet on goto */
---------------------------------------------------------------------
1) print A B C D .... Z
2) print A B B C C D.....upto Z
3) print n'th table
Ex:-e
10 x 1 =10
10 x 2 =20
10 x 3 =30
...............
10 x 10 =100
/* work sheet on loops */
---------------------------------------------------------------------
1) program to print 10 to 1
2) print a....z

5) program to print first n numbers sum..
10 number sum is 55
6)print 5 4 3 2 1 0 1 2 3 4 5
7) accespt a number and print digit sum use loops
8)Accept a number and test wether a number is prime number or
not
9)Find Sum of Natural Numbers
10)Find Factorial of a Number
11)Generate Multiplication Table
12)Count Number of Digits of an Integer
13)Reverse a Number
14)Calculate the Power of a Number
15)Check Whether a Number is Palindrome or Not
16)Check Whether an Integer is Prime or Not
17)Display Prime Numbers Between Two Intervals
18)Check Armstrong Number
19)Display Armstrong Number Between Two Intervals
20)Display Factors of a Number
21)Print Pyramids and Triangles in C programming using Loops
different patterns
22)Make a Simple Calculator to Add, Subtract, Multiply or
Divide Using switch...case
