在main函数中,我们调用reverseString函数来逆序字符串,并打印逆序前后的字符串。

“We use the reverse string function whenever we are required to change or reverse the order of string in a program. For example, if we have initially declared a char string of memory size 5 as “cloth”, now if we want to apply the string reversal operation on this string, then we ...
is not completely correct and may not find all calls of a function. This is mainly true for calls that are done via function pointers. Calltree is able to detect recursive function calls (e.g. functions that call themselves). Recursive function calls are marked with an ellipsis in the ...

Implement a function void reverse(char* str) in C or C++ which reverses a null-terminated string.This is (implicitly) asking for an in-place reversal of the string. We start by finding the end of the string (or equivalently, its length). Then we swap the last character and the first ...
Write a function reverse(s) that reverses the character string s . Use it to write a program that reverses its input a line at a time. #include #defin
C String function – Strrchr char*strrchr(char*str,intch) It is similar to the function strchr, the only difference is that it searches the string in reverse order, now you would have understood why we have extra r in strrchr, yes you guessed it correct, it is for reverse only. ...
