C Language Fifth time assignment

1. Taxi Pricing

#include <stdio.h>#include<math.h>intMain () {Doubles,m; intm1=0, m2=0; intt=0, n=0; printf ("Please enter mileage s=%d\n"); printf ("Please enter the waiting time t=%d\n"); scanf ("%d", s); scanf ("%d", T); if(s<=3) printf ("%d", m1=Ten); Else if(s>=3&&s<=Ten) printf ("%d", m1=Ten+2* (S-3)); Else{printf ("%d", m1= (S-Ten)*3+ (S-3)*2+Ten);} if(t<5) {m2=0; }    Else{        intm2=t/5+0.5; } m=m1+m2; printf ("Total fare =%d", M); scanf ("%d",&m); return 0; }

2.3 Numbers

#include <stdio.h>intMain () {intA,b,c,n; printf ("Please enter three numbers separated by a space \ n"); scanf (" %d%d%d",&a,&b,&c); if(a>b) {n=A; A=b; b=N; }    if(a>c) {n=A; A=B; C=N; }    if(b>c) {n=b; b=B; C=N; } printf (" %d%d%d", A,b,c); return 0; } 

3. Student Achievement

#include <stdio.h>intMain () {Chargrade; printf ("Enter level five score: \ n"); scanf ("%c",&grade); Switch(grade) { Case'A': printf ("90~100\n");  Break;  Case'B': printf ("80~89\n");  Break;  Case'C': printf ("70~79\n");  Break;  Case'D': printf ("60~69\n");  Break;  Case'E': printf ("0~59\n");  Break; default: printf ("fault\n");  Break; }     return 0;}

4. Triangles

 #include <stdio.h>int   main () {     int   I,j;  for  (J=1 ; J<=10 ; J++ for  (I=1 ; I<=j;i++) printf (  *   ); printf (  \n   "    );  return  0  ;} 

5. Expressway speeding penalty (not very clear)

#include <stdio.h>intMain () {Doublen,m,b; printf ("Please enter the speed limit and the actual speed, separated by a space:"); scanf ("%LF%LF",&n,&m); if(m>n&&m<b)DoubleB= (Double) (N-M) * -/m; if(b>Ten)    {        if(b>Ten&&b< -) printf ("A fine of $200"); Else if(b> -) printf ("revoke a driver's license"); }    Elseprintf ("not to be punished"); return 0; }

The fifth triangle in the book does not judge. It's so hard.
