1. Find the maximum value in three numbers

  <span style= "FONT-SIZE:14PX;" ></span><pre name= "code" class= "CPP" ><span style= "FONT-SIZE:14PX;"    >//Method 1: Find the maximum of two numbers first, then compare the .</span> int n1 = 0 with the maximum and the third, N2 = 0, n3 = 0;    printf ("Please enter three number: \ n");        scanf ("%d%d%d", &n1, &n2, &AMP;N3);    int max = 0;//defines a maximum value with an initial value of 0 if (N1 > n2) {max = N1;    } else {max = N2; }//Replace with a conditional expression with max = n1 > n2?    N1:N2;    if (Max < n3) {max = N3; }//max = max > n3?    Max:n3;    printf (maximum: max =%d, max); Method 2: Use N1 respectively and N2, N3 comparison. <pre name= "code" class= "CPP" ><pre name= "code" class= "CPP" >    int    N1 = 0, N2 = 0, n3 = 0;    printf ("Please enter three number: \ n");    scanf ("%d%d%d", &n1, &AMP;N2, &AMP;N3);    int max = 0;    if (N1 >n2) {        I F (N1 > N3) {            max = n1;       } else {            max = n3;        }   } else if (N2 > N3) {     & nbsp;  max = n2;   } else {        max = n3;   } Equivalent to Max = n1 > n2? N1 > N3? N1:n3:n2? n3:n2:n3    printf (maximum: max =%d, max);

 

2. Enter three numbers to print out the middle value (i.e. the second largest value) in two ways
Tip: First, the maximum minimum is first, and the second, only the conditional operator is used

      Method 1 float x = 0.0;     Float y = 0.0;     float z = 0.0; float max = 0.0;//define max float min = 0.0;//define minimum float mid = 0.0;//Define intermediate value printf ("Please input three number:\n")     ;         scanf ("%f%f%f", &x, &y, &z); max = x > y? x > Z? X:z: y > Z?    Y:z; min = x < y? x < Z? X:z: Y < z?        Y:z;    Mid = x + y + z-min-max;          printf ("The mid number is:%.2f\n", mid);    Method 2 float x = 0.0;    Float y = 0.0;    float z = 0.0;    float max = 0.0;//defines the maximum value of float min = 0.0;//defines the minimum value of float mid = 0.0;//defines the median value printf ("Please input three number:\n");    scanf ("%f%f%f", &x, &y, &z);        if (x >= y) {if (y >= z) {mid = y;            } else {if (x <= z) {mid = X;            } else {mid = Z;        }}}} else {if (y <= z) {mid = y;        } else if (x > z) {mid = y; } else {mid = x;     }} printf ("The mid number is:%.2f\n", mid);
