Comprehensive Guide to C Language String Operations (Very Detailed)

Strings are surprisingly the most difficult part in C!

1) String Operations strcpy(p, p1) Copy string strncpy(p, p1, n) Copy specified length string strcat(p, p1) Append string strncat(p, p1, n) Append specified length string strlen(p) Get string length strcmp(p, p1) Compare strings strcasecmp Case-insensitive string comparison strncmp(p, p1, n) Compare specified length strings strchr(p, c) Find specified character in string strrchr(p, c) Find character in string (reverse search) strstr(p, p1) Find substring strpbrk(p, p1) Find the first occurrence of any character from a set of characters (p1) in the current string (p) strspn(p, p1) Find the length of the initial segment of string (p) that consists entirely of characters from a set (p1) strcspn(p, p1) Find the length of the initial segment of string (p) that consists entirely of characters NOT from a set (p1) * String manipulation functions with specified length fill with null terminators after the processed string.

2) String to Numeric Type Conversion strtod(p, ppend) Converts a
