Which of the library function put back the length of a string?a.strlenb.strcatc.strcmpd.strcpy
Question
Which of the library function put back the length of a string?a.strlenb.strcatc.strcmpd.strcpy
Solution 1
To determine which library function puts back the length of a string, we can analyze the given options:
a. strlen: This function returns the length of a string, but it does not put the length back into the string itself.
b. strcat: This function concatenates two strings, but it does not modify the length of the original string.
c. strcmp: This function compares two strings and returns an integer value based on their lexicographical order. It does not modify the length of the string.
d. strcpy: This function copies the contents of one string into another, including the null character at the end. However, it does not modify the length of the string.
Based on the analysis, none of the given options put back the length of a string.
