WebJan 5, 2024 · Introduction. Suppose we have $4$ unsigned values, $3$, $8$, $15$, and $1$, and we want to save these values as binary values to a file. In a modern computer, the minimal IO bit-width is $8$ bits, i.e., $1$ byte, $1$ byte could represent an unsigned values from $0$ to $255$, and the $4$ unsigned values we want to save are just within the … WebParses str interpreting its content as an integral number of the specified base, which is returned as an int value. If idx is not a null pointer, the function also sets the value of idx to the position of the first character in str after the number. The function uses strtol (or wcstol) to perform the conversion (see strtol for more details on the process). ... foldable 3ply fruit plate
