Calculate the Sum of Numbers

You can put almost whatever you want inside a function. The purpose of the function is to save the code, and execute it when you need it.

Example
void calculateSum() {
  int x = 5;
  int y = 10;
  int sum = x + y;
  printf("The sum of x + y is: %d", sum);
}

int main() {
  calculateSum();  // call the function
  return 0;
}

 42 day  C Structures The structure in C is a user-defined data type that can be used to group items of possibly different types into a single type. The struct keyword is used to define the structure in the C programming language. The items in the structure are called its member and they can be of any valid data type. Additionally, the values of a structure are stored in contiguous memory locations. Syntax struct structure_name {     data_type member_name1;     data_type member_name1;     ....     .... };

 40 day  Arrays  Properties of Arrays in C It is very important to understand the properties of the C array so that we can avoid bugs while using it. The following are the main properties of an array in C: 1. Fixed Size The array in C is a fixed-size collection of elements. The size of the array must be known at the compile time and it cannot be changed once it is declared. 2. Homogeneous Collection We can only store one type of element in an array. There is no restriction on the number of elements but the type of all of these elements must be the same. 3. Indexing in Array The array index always starts with 0 in C language. It means that the index of the first element of the array will be 0 and the last element will be N – 1. 4. Dimensions of an Array A dimension of an array is the number of indexes required to refer to an element in the array. It is the number of directions in which you can grow the array size. 5. Contiguous Storage All the elements in the array are sto...
