C语言 if语句

if (condition)
{
     //Block of C statements here
     //These statements will only execute if the condition is true
}

#include <stdio.h>
int main()
{
    int x = 20;
    int y = 22;
    if (x<y)
    {
        printf("Variable x is less than y");
    }
    return 0;
}

Variable x is less than y

#include <stdio.h>
int main()
{
    int x, y;
    printf("enter the value of x:");
    scanf("%d", &x);
    printf("enter the value of y:");
    scanf("%d", &y);
    if (x>y)
    {
    printf("x is greater than y\n");
    }
    if (x<y)
    {
    printf("x is less than y\n");
    }
    if (x==y)
    {
    printf("x is equal to y\n");
    }
    printf("End of Program");
    return 0;
}

enter the value of x:20
enter the value of y:20
x is equal to y
End of Program
