"The second argument to strcpy() is marked as const, indicating that it will not be changed. The contents of the first argument will be changed since we are copying a string into it, erasing whatever contents it had prior. Finally, the function returns a pointer to the dest argument, mostly so that it can be used in nested function calls (though we’ll avoid such confusingly terse “tricks”). From our example:\n\n1 //\"assign\" (copy) \"Tom Waits\" into the string fullName:\n\n2 strcpy(fullName, \"Tom Waits\");\n\nIn addition, we can access and modify individual characters in a string using the usual indexing and assignment operator with char literals.\n\n1 //access individual characters:\n\n2 char firstInitial = fullName[0]; //'T'\n\n3 char lastInitial = fullName[4]; //'W'\n\n4\n\n5 //printing:\n\n6 printf(\"First Initial: %c\n\n\", fullName[0]);\n\n7\n\n8 //modifying:\n\n9 firstInitial[0] = 't';\n\n10 firstInitial[4] = 'w';\n\n11 //fullName is now \"tom waits\""
