- What do you mean by Arrays? Give one example of array and how you can declare an array. Definition: An array is a collection of similar data types stored at contiguous memory locations. It helps to store multiple values in a single variable instead of declaring separate variables. Example: C #include <stdio.h> int main() f int marks[5] =[85,90,78,88,92；1/ declaration and initialization of array printf("First student marks:%d",marks[0]);return 0; Explanation: int marks[5];→ declares an array of 5integers. marks[0] → represents the first element of the array. 2.What do you mean by Functions?Write the types of functions and give one example in code of each type. Definition: A function is a block of code that performs a specific task. It helps in code reusability and easy debugging. Types of Functions: 1.Library (Predefined) Function 2.User-defined Function (a) Library Function Example:
#include <stdio.h>#include <math.h>int main()[ double result = sqrt(25)；1/ using predefined sqrt() function printf("Square root:%.2f", result);return 0; (b) User-defined Function Example: C #include <stdio.h> void greet()f 1/ function definition printf("Hello, welcome to C programming!"); 人 int main() f greet(); return 0; 1/ function call 子 3. What do you mean by Pointers?Write a code how you can initialize the pointer. Definition: A pointer is a variable that stores the memory address of another variable. Example Code: C #include <stdio.h> int main() f int num = 10;int *ptr;1/ pointer declaration ptr = #pointer initialization printf("Value of num:%d\n",num);printf("Address of num:%pln", ptr); printf("Value using pointer:%d\n", *ptr);return 0; 人 Explanation: *ptr -→ pointer variable. &num -→ gives address of variable num. tptr -→ gives value stored at that address. 4.What are the types of Array?Write in code (1D & 2D included). Types of Arrays: 1.One Dimensional (1D) Array 2.Two Dimensional (2D) Array 3. Multi Dimensional Array (a) One Dimensional Array Example: C #include <stdio.h> int main() f int numbers[5]=(1，2，3，4，5)； for(int i= 0;i<5;i++)[ printf("%d "，numbers[i]); return 0; 子 (b) Two Dimensional Array Example:
#include <stdio.h> int main()[ int matrix[2][3]=f 11，2，3)， 14，5，60 for(int i=0;i<2；i++)[ for(int j=0;j<3；j++)f printf("%d",matrixli]lj]);printf("\n")； return 0; 5.Explain the types of Operators in code. Operators in C: Operators are special symbols that perform operations on operands (variables or values). Types of Operators: Type Example Descrir Arithmetic + 大 /% Mather operati Relational <=i <>=<= Compe Logical Assignment && =/=* Assign Increment/Decrement Increas valuet 十十 へVYく & Bitwise Example Code:
#include <stdio.h> int main()f int a = 10, b=5; 1/ Arithmetic printf("Addition:%d\n", a + b); 1/ Relational printf("Is a > b? %d'n", a >b); 1/ Logical printf("Logical AND:%d\n", (a >b) && (b>0))； 1/ Assignment a += b;/l a=a + b printf("After assignment:%d\n", a); 1/ Increment/Decrement a++; printf("After increment:%d\n",a);return 0;
