Step 2 of 6
strlen and friends
<string.h> has the standard string functions:
| Function | Does |
|---|---|
strlen(s) |
number of chars before '\0' |
strcpy(dst, src) |
copy src into dst |
strcat(dst, src) |
append src to dst |
strcmp(a, b) |
0 if equal, negative/positive otherwise |
dst must be big enough, including room for the '\0'.
Your turn: read two words and print them joined with a - between, followed by the total length. Input de dust2 prints de-dust2 8.
