C語言 strcpy的實現

return strlen i++ urn abc tdi void abcde abcd

#include<stdio.h> #include<stdlib.h> void mystr(char *arr2, char *arr1,int length) { int i; for (i = 0; i < length; i++) { if (*(arr1+i) != ‘\0‘) { *(arr2 + i) = *(arr1 + i); } } } int main() { char arr1[]= "abcde"; char arr2[]= " "; int length = strlen(arr1); mystr(arr2, arr1,length); printf("%s", arr2); system("pause"); return 0; }
