1. For integer, there are some functions that can be specially converted on various platforms, such as itoa.

However, it is more common to use the sprintf function. ?

2. Statement:

int sprintf(char *dst，const char *format_string，...);

The header file is stdio.h

3. Function:

Sprintf is an indefinite parameter function. According to the format characters provided in format_string, the subsequent parameters are converted into strings and stored in the first parameter dst.

4. Use examples:

Short? a = 1；

int？ b = 2；

Dragon? c = 3；

Floating? d = 4；

Charles? buf[ 100]；

sprintf(buf，？ " %hd？ %d？ %ld？ %f”，a，b，c，d)； //According to the format, four variables are stored in a string. After execution, the string in buf is "1 2 3 4.000000".

Format strings are used in the same way as the output function printf. ?
