How do you input a string in the C language?

In the C language, we can use the scanf function to input a string.

char str[100];  // 声明一个字符数组存储字符串

printf("请输入字符串：");
scanf("%s", str);  // 输入字符串并存储到str数组中

printf("您输入的字符串是：%s\n", str);  // 输出输入的字符串

It is important to note that the scanf function stops reading when it encounters a space or enter while reading a string, so if you need to input a string containing spaces, you can use the fgets function instead.

char str[100];  // 声明一个字符数组存储字符串

printf("请输入字符串：");
fgets(str, sizeof(str), stdin);  // 输入字符串并存储到str数组中

printf("您输入的字符串是：%s\n", str);  // 输出输入的字符串

When using the fgets function, you need to specify the size of the array to store the string and pass stdin as the third parameter.
