C Programmers often requires obtaining a duplicate string from an original one. This can be achieved by knowing the length of the string and then allocating the buffer for the string and finally copying the content to the allocated buffer.
We do not require to do all the steps as C runtime library has strdup() function to do all these for us. Here is a sample example program.
Note: Buffer allocated by strdup should be released with free(). strtok(), strrev() etc are some utility functions modify its input buffer and produce the result. This is why we should not pass a constant string. CPU will produce a access violation while execution. strdup() is usedful for these cases.
