今天和大家继续分享关于C语言函数库的知识,特别是常用的字符串输出函数。

  • printf函数
  • printf("格式字符串", 输出项1, 输出项2, ...) 这是最常用的格式化输出函数。格式字符串中使用%符号控制输出类型。例如:

    #include 
    int main() { int i = 10; printf("i=%d\n", i); return 0;}
    1. puts函数
    2. puts()函数用于输出字符串。直接将字符串传递给函数即可。例如:

      #include 
      int main() { char a[] = "I love you!"; puts(a); return 0;}
      1. putchar函数
      2. putchar()函数用于输出单个字符,适合逐个处理大字符串中的字符。例如:

        #include 
        int main() { char a[] = "I love you!"; int i = 0; for (; i < 12; i++) { putchar(a[i]); } return 0;}

        这些函数是C语言中处理字符串输出的常用工具,熟练掌握它们能显著提高开发效率。如果需要更深入的学习,欢迎继续关注我们。
