Passing Values to Functions

how do i pass a value to a function?
lets say i wanna pass an array of string to a function

char array[50];
printf("Enter a string:")
scanf("%s",array);

how do i pass this array to a function like
void InsertString(struct node**S,char array[50]{
}
??

If you are passing a pointer to a function:
functionName(&variable);

If you are passing an array:
functionName(array);
or
functionName(&array[0]);

Otherwise:
functionName(variable);

Look at this:

Code:

---

typedef struct Node
{
 Node *next;

 char string[50];
 
 Node *prev;
};


int InsertString(Node *n, char *c, int maxlen)
{
 int len = strlen(c);

 if(len > maxlen)
 return -1;

 if(len < 1)
 return -2;
 
 strcpy(n->string, c);
 
 return 1;
}





int main()
{

Node *thisNode = (Node *)malloc(sizeof(Node));

if(thisNode == NULL)  //couldn't allocate...
return 0;

char string[] = "I am a programmer. But why?";

int valid = InsertString(thisNode, string, 50);// struct allows 50 ch.

if(!valid)
{
 switch(valid)
 {
  case -1: printf("String was too big!");
  break;
 
  case -2: printf("String was empty!");
  break;
 
  default: printf("Undefined problem with string!");
  }
}





return 0;
}

Just a simple example of passing parameters, utilizing return values, and using switch statements...

...also notice that if you "typedef" a struct, you can declare variables of it's type and likewise declare in function parameters as if it were an int, double, etc. , that is, without using the "struct" keyword.

...happy coding.
