1. Please write a C function that searches for a given character in a given memory area and returns the index value of the character's location.
Answer:
int search(char *cpSource, int n, char ch)
{
}
2. A singly linked list, with an unknown head node, and a pointer pointing to one of the nodes. How to delete the node pointed to by this pointer?
Answer:
Copy the value of the next node pointed to by this pointer to this node, set next to next->next, and then delete the node pointed to by next.
3. Write a function to compare the sizes of two strings str1 and str2. If they are equal, it returns 0; if str1 is greater than str2, it returns 1; if str1 is less than str2, it returns -1.
Answer:
int strcmp ( const char * src,const char * dst)
{
}
