Help me in C

Help me in C

Help me in C

(OP)
In programming language 'C' can we change the value of a variable without touching the variable in any sense?

RE: Help me in C

Yes we can
by the use of pointers.
That is what we do by in writing functions

RE: Help me in C

A bit more detail with an example:

//Declare an integer variable val and initialize it
int val = 0;

//Get the address of the variable 'val
int *pVal = &val;

//Change the value of the variable val without
//touching the variable name 'val'

*pVal = 10;

// Now, you've changed the value of val
