What does ║ represent in C language?

In C language, "║" represents a vertical dividing line, which is used to format output and align text vertically. Usage includes: As a format specifier in a format control string for the printf() and scanf() functions. Specifies the output width (for example, "M" represents a 4-bit wide integer). Specifies the precision of the floating point number (for example, "%8.2f" means an 8-bit wide, two decimal place floating point number). Align the output vertically (for example, "M║%8.2f║" aligns integers and floating point numbers).

The "║" symbol in C language represents a vertical dividing line

The "║" symbol in C language Represents a vertical separator line, used to format output. It vertically aligns the text in the output stream and pads spaces to the expected width.

Usage:

The "║" symbol is used as a format specifier in the format control string of the printf() and scanf() functions. The following syntax illustrates its usage:

<code class="C">printf("%[旗标][宽度][长度说明符]║[精度][类型标志]║", 变量/表达式);</code>

Where:

• Flags: Optional, used to specify alignment (e.g. '-' means left alignment)
• Width: Optional, specifies the width of the output (in characters)
• Length specifier: Optional, specifies the length of the variable (For example, 'h' represents a short integer)
• Precision: Optional, specifies the precision of floating point numbers
• Type flag: Specifies the type of the variable (e.g. 'd' means integer)

Example:

<code class="C">#include <stdio.h>

int main() {
    int num1 = 123;
    double num2 = 45.67;

    printf("%4d║%8.2f║\n", num1, num2);

    return 0;
}</code>

Output:

<code>  123║   45.67║</code>

In this example, the output is formatted Is a 4-character wide integer (padded with spaces) and an 8-character wide floating point number (two decimal places). The "║" symbol aligns the output vertically.
