A, B and C are three 3×3 matrices containing real elements.

A, B and C are three 3×3 matrices containing real elements.

a) Write a ‘C’ function to input from user appropriate values into matrices A and B. Use
suitable loops. Make use of pointers if necessary.
b) Write a ‘C’ function to calculate matrix C such that C=A+B Use suitable loops. Make use of pointers if necessary
c) Write a ‘C’ program to call the above two functions and print Matrix C suitably. Write suitable prototype etc. Use suitable loops. Make use of pointers if necessary

Size of all elements in a union should be same.

Each statement below is either TRUE or FALSE. Choose the most appropriate one
and ENTER in the “tear-off” sheet attached to the question paper, following
instructions therein.

2.1 A structure can contain pointer to itself.
2.2 Size of all elements in a union should be same.
2.3 Size of a pointer is equal to the data type it points to.
2.4 In ‘C’, the compiler does not check if the subscript used for an array exceeds size of the array.
2.5 A ‘for’ loop in ‘C’ has three statements, namely, assignment, test and increment statements.
2.6 cout and cin can be used for output and input respectively in ‘C’ language.
2.7 The default initial value of a static int variable is zero.
2.8 Binary search can be easily performed on a linked list.
2.9 A function name can be passed as an argument to another function.
2.10 A ‘C’ function can contain many return statements.
