The 'if' structure is for conditional checks, while 'switch' is for evaluating multiple cases based on a single expression.

'if' is a function, while 'switch' is a variable type.

'if' is used for loops, while 'switch' is for single conditions.

'if' can only handle two cases, whereas 'switch' can handle more than two.

A function in C is a variable that stores data.

A function in C is a type of loop used for iteration.

A function in C is a block of code defined with a return type, name, and parameters, used to perform specific tasks.

A function in C is a keyword that defines a data structure.

A function to calculate the sum of an array: function sum(arr) { return arr.reduce((a, b) => a + b, 0); }

A function to reverse a string iteratively: function reverse(str) { let reversed = ''; for (let i = str.length - 1; i >= 0; i--) { reversed += str[i]; } return reversed; }

A function to find the maximum number in an array: function max(arr) { return Math.max(...arr); }

A recursive function to calculate factorial: function factorial(n) { if (n === 0) { return 1; } else { return n * factorial(n - 1); } }

A pointer in C is a special kind of loop used for iteration.

A pointer in C is a type of function that returns a variable.

A pointer in C is a variable that stores a string value.

A pointer in C is a variable that holds the address of another variable, used for direct memory access and manipulation.

Use malloc(), calloc(), realloc(), and free() functions.

Use printf() to allocate memory.

Use free() to allocate memory.

Use strcpy() for dynamic memory allocation.

To manage memory allocation in C.

To define functions in C.

The purpose of a structure in C is to group different data types into a single unit.

To create loops in C.

A structure allocates separate memory for each member, while a union shares the same memory for all members.

A union can only contain integer types, while a structure can contain any data type.

A structure can hold only one type of data, while a union can hold multiple types.

A structure is faster to access than a union because it uses less memory.

Decision making in C programming involves defining variables only.

Decision making in C programming refers to the use of control structures to execute different actions based on conditions.

Decision making in C programming is about writing comments.

Decision making in C programming refers to the use of loops for iteration.

for(i = 0; i < n; i++) // code to execute

for(int i = 0; i < n; i++) // execute code here

for(int i = 0; i < n; i++) { code to execute }

for(int i = 0; i < n; i++) { // code to execute }
