There are 4 storage classes in C: auto register static extern At least a few of these will look familiar to anyone who has done a cursory amount of Objective-C programming. Let’s go into more detail with each one: auto There’s a good chance you’ve never seen this keyword in the ...
According to the storage classes of “c” the lifetime of the auto variable is restricted within the body that’s why how many times we are calling the abc function that many times it will created. void xyz() { int a=5; --a; printf(“\na=%d”,a); } void main() { auto int ...
Static Storage Class Program Programming Example 3 #include<stdio.h> voidf1(); intmain() { f1(); f1(); return0; } voidf1() { inti=0; i++; printf("i=%d\n",i); } Output Explanation Here we get result two 1 because we declare the variable by default Auto. ...
