In the C programming language, you can use the scanf function to input strings. Here are some commonly used methods:

  1. Utilizing the %s format specifier:
char str[100];
printf("请输入一个字符串：");
scanf("%s", str);

This method will read a string from standard input and store it in the str array. Input will stop when encountering a space or newline character.

  1. Use the %[^\n] format specifier:
char str[100];
printf("请输入一个字符串：");
scanf(" %[^\n]", str);

This method will read all characters except for line breaks and store them in an array called str.

  1. Use the fgets function:
char str[100];
printf("请输入一个字符串：");
fgets(str, sizeof(str), stdin);

This method will read a line of string from the standard input and store it in the str array.

It is important to note that all of the above methods will automatically add a null character ‘\0’ at the end of the string to indicate the end of the string.
