Wsprintf has three parameters. The first two are buffer and format. Buffer and format are provided. The format only contains the format "% s, how to output the string represented by every % S. For example, if the buffer is "abcdab1234" and the format is "% SAB % s34", the output substring should be "ABCD" and "12 ".

format part 1 is     --- %sformat part 2 is     --- abformat part 3 is     --- %sformat part 4 is     --- 34the %s is abcdthe %s is 12Press any key to continue
