} if-else 语句: c if (x > 0) { printf("x is positive\n"); } else { printf("x is non-positive\n"); } switch 语句: c switch (x) { case 1: printf("One\n"); break; case 2: printf("Two\n"); break; default: printf("Other\
They are referred to as if-else conditional statements or if-else C++ for short.In this article, we will examine the different types of decision-making statements in C++ programming. These include simple if statements, if-else statements, nested if, if else, if ladder, and jump statements. ...
We can have multiple branches of conditions with additional else if statements. if_else_if.c #include #include <stdio.h> #include <stdlib.h> int main() { srand(time(NULL)); int r = rand() % 10 - 5; printf("%d\n", r); if (r > 0){ printf("The number is positive\n...
if(cond){ ... statements; ...}else{ ... statements; ...}可是有时候 cond 只在极少的情况下发生,例如:随机生成一个随机数,该随机数的范围是 0~100000,如果随机数小于 2,则将 val 赋值为 -1,否则将 val 赋值为当前UTC时间,相关C语言代码如下,请看: if(myrand() < 2) val = -1;else val =...

Modify the revised program earlier by replacing the two if statements with a single if/else statement. Run the program again to test the results. 123456789101112131415161718192021222324252627282930313233 // This program tests whether or not an initialized value // is equal to a...
The statement or statements in the then-statement and the else-statement can be of any kind, including another if statement nested inside the original if statement. In nested if statements, each else clause belongs to the last if that doesn’t have a corresponding else. In the following examp...
