A.     Number Frequency-Arrays

1. Write a program to count the number of 10’s in the given list of 15 numbers. The output should look like:                                                                                                        [01]
2. Extend your program to work with a list of n numbers.                                         [01]

                                                                                  

          Random Numbers-Methods

1. Write a program to generate a 10 Random Numbers:                                           [01]
2. Extend your program to generate n Random numbers.                                         [01]

B.    Word Count -String Processing

1. Write a program to count the occurrence of word “an” in the string.               [01]
2. Extend your program to count the occurrence of string being input in the string.

               [01]

C.      Recursion

          By using recursion, write a program to:

1. Print digits in a number.                                                                                                                [01]
2. Find sum of digits of a number.                                                                                                  [01]

D.        Matrix Manipulation

Write a C# program to Perform Matrix Multiplication.                                                                      [02]

Note:-

The matrix multiplication can be performed only if:

• The number of columns of the first matrix is equal to
• The number of rows of the second matrix

Ok sorry for that , i need only (A) section.

   int list[15]={33,5,11,10,6,10,54,1,2,10,45,55,10,14,51},i,c=0;//initially count of 10's is 0
   for(i=0;i<15;i++)
   {
       if(list[i]==10)
           c++; //counts no.of 10's in an array
   }
   printf("number of 10's in the given list of 15 numbers: %d",c);
