scope of a variable is the part of the code within which the variable is defined or the part of your code within which the th variable can be used for example
#include<stdio.h>
void main()
{
int variable1
}
now this variable (variable1) that we have used can be used anywhere within the main function .but if i write a code as shown below
#include<stdio.h>
void function1(int a)
void main()
{
int variable1
}
void function1(int a)
{
sum=variable1+variable1;
}
the compiler wouldn't know what variable1 ,being used in function1 is.
we therefore say that variable1 has a scope within the main only
if however we would have written int 'variable1' immediately after #include<stdio.h> then 'variable one would have been a global variable and could have been used anywhere within the code

∙ 10y agoA variable is a named memory location, used to store various types of data. The type of variable determines its size in memory, range of values that can be stored in it and type of operations that can be performed on it. A variable name can be created using letters, digits and underscore character. All variables should start with a letter or an underscore character and must be declared before using them in a program.

How do you swap in c programming?
the simple way can be explained by example as: let there be two integers as : int a=10,b=5; if we want to use third variable then let third variable be int c; and sorting is done as : c=a; a=b; b=c; if it is to be done by without using third variable then : a=a+b; b=a-b; a=a-b; at last the variable is sorted.
