1、if语句嵌套
int a = 10;
int b = 30;
int c = 20;
int max;
if (a > b) {
if (a > c) {
max = a;
} else {
max = c;
}
} else {
if (b > c) {
max = b;
} else {
max = c;
}
}
2、if语句
int a = 10;
int b = 30;
int c = 20;
int max;
if (a > b) {
max = a;
} else {
max = b;
}
if (max < c) {
max = c;
}
3、if语句(假定a最大,b,c与a比较,如果比a大,则赋值给max)
int a = 10;
int b = 30;
int c = 20;
int max = a;
if (b > max) {
max = b;
}
if (c > max) {
max = c;
}
4、三元运算符
int a = 10;
int b = 30;
int c = 20;
int max = (a > b) ? a : b;
max = (max > c) ? max : c;
或者
int max = ((a > b ? a : b) > c) ? (a > b ? a : b) : c;(建议不用这种)
5、if语句 + 逻辑运算符 &&(a,b,c三个数,如果不是a最大,或者b最大,就是c最大)
int a = 10;
int b = 30;
int c = 20;
int max;
if (a > b && a > c) {
max = a;
} else if (c > a && c > b) {
max = c;
} else
max = b;
