auto and static variables in c
What is auto variable in C?
In C, an auto variable is a local variable automatically created and destroyed within a block or function. The auto keyword is optional when declaring variables within a block or function, as it is the default storage class for local variables. In this example, the printNumbers () function demonstrates the usage of auto variables.
What is the difference between a static variable and a normal variable?
1) A static int variable remains in memory while the program is running. A normal or auto variable is destroyed when a function call where the variable was declared is over. For example, we can use static int to count the number of times a function is called, but an auto variable can’t be used for this purpose.
How can we access auto and static variables outside their scope in C?
How we can access auto and static variables outside their scope in C? Auto and static variable have scope limited to the block in which they are defined. Since Auto variables are defined in the stack, if the function exits, stack is destroyed and memory for the auto variable is released.
What is the difference between static and auto variables?
Static variables are initialized to zero by default if no explicit initialization is provided. Scope: Auto variables have block scope, which means they are visible and accessible only within the block or function in which they are declared. They cannot be accessed from outside the block or function.
