What is Traversing of an array?
The process of visiting each and every element of an array in a specific order is called Traversing an array.
This can be done using a loop, such as a for loop or a while loop.

What is meant by insertion?
Placing a new element at a specified position of an array is called as insertion.
This operation can help maintain the order or structure of data within the array.

C Programming Codes
#include<stdio.h> int main() { int i; i=printf("Hello world"); printf(" %d",i); return 0; }
Explaination:
This program prints "Hello world" with printf() , and returns value 11, (the character count) which is assigned to variable i. Then, it uses printf again to display the value of i. The program's output will be "Hello world 11"
