Challenging Programming Problems -Part II

 [Q001] Write a program (W.A.P.) in C to clear the screen and print "Freshersworld" on each line, forming a diagonal pattern running from upper-left to lower right.[Use suitable delay]

 
[Q002] W.A.P. in C to SORT the array of strings based on first 3-LETTERS ONLY.

 
[Q003] Some C Functions take variable argument list in addition to taking a number of fixed (known) parameters. Implement using USER-DEFINED C FUNCTION that take VARIABLE ARGUMENT LIST and COMPUTE THE SUM OF VALUES specified in the list.
 Ex: int Sum(int a,...) // Here ... means VARIABLE ARGUMENT LIST
       {
            // Your Code Goes Here to access the values in the variable argument list
       }
       void main(void)
       {
            printf("%d",Sum(5,6,7,8,9,10)); // Prints the RESULT (Sum of these values=45)
       }

   
[Q004] W.A.P. in C to compute the sum of two values using function that takes two arguments (INTEGERS) and IT SHOULD RETURN the sum WITHOUT USING the RETURN statement but the return type of function is INTEGER ('int' data type). [NOTE : DO NOT MAKE USE OF ANY GLOBAL VARIABLES OR POINTER CONCEPT]

 
[Q005] W.A.P. in C to SWAP the contents of TWO VARIABLES WITHOUT using ASSIGNMENT OPERATOR.
[HINT : USE 'asm' statement]

 [Q006] W.A.P. in C to FIND THE LARGEST of two numbers (integer) WITHOUT using ?:  operator, if, if...else and switch statements. [HINT : USE 'asm' statement]
 

 
 [Q007] W.A.P. in C to print the following output WITHOUT USING GOTO STATEMENT, CONDITIONAL STATEMENTS (if, if...else & switch statements) and ANY LOOP STATEMENTS (for, while & do..while) :
 (a)
     *****
     ****
     ***
     **
     *

 (b)
     *
     **
     ***
     ****
     *****

 
[Q008] W.A.P. in C to REVERSE THE WORDS IN A GIVEN LINE OF TEXT. [HINT : USE Built-in function 'strtok' in 'string.h' header file]

  
[Q009] W.A.P. in C to CONVERT THE TEXT within /* ... */ to UPPER-CASE (all occurrences) from the SPECIFIED C Source Code File and save the file without altering the remaining text.

Solutions for the above queries.
