如果您和曾经的我一样是C语言的初学者,您有可能时常遇到那些“奇异”的字符串处理问题,例如,int里的数转成char数组字符串类型,在char数组中间插入或者删除什么东西,等等。要是采用传统方式这样操作相当令人头大,有时您可能会想要是有一个类似printf的函数能够直接输出到字符串里该多香。
snprintf() C 标准库 - <stdio.h> 描述 snprintf() 是一个 C 语言标准库函数,用于格式化输出字符串,并将结果写入到指定的缓冲区,与 sprintf() 不同的是,snprintf() 会限制输出的字符数,避免缓冲区溢出。 与sprintf()函数不同的是,snprintf() 函数提供了一个参数 size,可以防止缓冲区溢出。如果格式化后的字...
The snprintf() function writes a formatted string followed by a \0 null terminating character into a char array.The snprintf() function is defined in the <stdio.h> header file.The format string can contain format specifiers which describe where and how to represent additional arguments that ...
The radix character is defined by language-specific data in the LC_NUMERIC category of the program's locale. In the C locale, or in a locale where the radix character is not defined, the radix character defaults to a . (dot). After any of these subroutines runs s...
