Hello friend as you want the Punjab Technical University, Jalandhar MCA 1st semester question papers so here I am providing you the same…. What do you mean by the terms algorithm and flowchart? Illustrate their use with the help of suitable examples? Q2) List and explain different types of data types in C?Also differentiate between signed and unsigned data types with reference to range of memory they occupy? (1 x 10: 10) Section - B Q3) What are functions? Differentiate between call by value and call by reference with the help of suitable examples? a4), Write a C program to read the element of two 3 x 3 matrices and multiply two main test Section - C (1x10-10) Q5) Write a function (using pointer parameters) that compares two integer arrays to see whether they are identical. The function returns I if they are identical, 0 otherwise? Q6) Differentiate and compare the working of an array, structure and a union with the help of suitable examples? Section – D Q7) Write a program that compares two files and returns 0 if they are equal and I if they are not. Q8) What do you mean by dynamic memory allocation? Explain the working of following functions with the help of suitable examples : . Malloc ( ) . Calloc ( ) . Free o . Realloc ( ) Section - E Differentiate between reserve words and identifiers? What are enumerated data types? What is sorting? What is the role of header files? Explain global variable and local variable. What do you mean by conditional statements.
