1. Temperature problems

#include <stdio.h>int  main () {    double  F, C;    scanf ("%lf", &f);     5 ) /9.0;    printf ("%.3lf\n", c);     return 0 ;}

Operation Result:

2. The question of averages

#include <stdio.h>int  main () {    int  A, B, C;    scanf ("%d%d%d", &a, &b, &c);     double d = (a+b+c)/3.0;    printf ("%.3lf\n", D);     return 0 ;}

Keep three decimal places%.3f

Operation Result:

3. Continuity and Problems

#include <stdio.h>int  main () {    int n=0, sum;      while 1 && scanf ("%d", &N));     = N (1+n)/2;    printf ("%d\n", sum);     return 0 ;}

Operation Result:

4. Sine and cosine problems

#include <stdio.h>#include<math.h>intMain () {Const DoublePI = ACOs (-1.0);//Pi uses ACOs (-1.0) to obtain M_PI is not ANSI C standard    intn =0;  while(N <1|| n >359) && scanf ("%d", &n));//1-359    Doubleth = n/180.0* PI;//Convert to Radian systemprintf"%LF%lf\n", sin (th), cos (th)); return 0;}

Operation Result:

5. Discount Issues

#include <stdio.h>intMain () {intn =0; DoubleAmount =0;  while(N <1&& scanf ("%d", &N)); if(n the>= -) Amount= N the*0.85; ElseAmount= N the; printf ("%.2lf\n", amount); return 0;}

Operation Result:

6. Triangle problem

#include <stdio.h>intMain () {intA =0, B =0, C =0;  while((A * b *c <1&& (a<1|| b<1|| c<1)) && (scanf ("%d%d%d", &a, &b, &c) <=3) {fflush (stdin);    }; if(! (A+b > C && a+c > B && b+c >a) printf ("Not a triangle\n"); Else    {     if(a*a + b*b = = C*c | | a*a + c*c = B*b | | b*b + C*C = = *a) printf ("yes\n"); Elseprintf ("no\n"); }    return 0;}

Operation Result:

7. Leap Year issues

#include <stdio.h>intMain () {inty =0;  while(Y <1&& scanf ("%d", &y) <=1) {fflush (stdin); }    if((y%4==0&& y% -!=0)|| (Y% -==0) {printf ("yes\n"); }    Else{printf ("no\n"); }    return 0;}

Conditions for leap years
Multiples of 4, but not multiples of 100
Or a multiple of 400.

Operation Result:
