C-Sixth week assignment

Topic

Topic One: Expressway speeding penalty

1. Experiment Code

#include <stdio.h>intMain () {intSpeed,maxspeed; Doublex; scanf ("%d%d",&speed,&maxspeed); X=(Double) (Speed-maxspeed)/(Double) maxspeed* -; if(x<Ten) printf ("OK"); Else if(x>= -) printf ("exceed%.0f%%. License revoked", x); Elseprintf ("exceed%.0f%%. Ticket", x); return 0;}

2. Design Ideas

① algorithm

Begin

Input Speed,maxspeed//indicates actual speed and lane speed limit respectively

Calculates the value of x//x as a percentage of the actual speed beyond the lane speed limit

Determine the size of the X value and output different results

End

Topic Two: Calculation of oil costs

1. Experiment Code

#include <stdio.h>intMain () {intA =0; floatB,price,discount,money; CharC; scanf ("%d%2f%c",&a,&b,&c); if(b = = -) { price=6.95; }    if(b = = the) { price=7.44; }    if(b = = the) { price=7.93; }    if(c = ='m') {Discount=0.05; }    if(c = ='e') {Discount=0.03; } Money= A * price * (1-discount); printf ("%.2f", Money); } 

2. Design Ideas

① algorithm

Begin

Input a,b,c//a for fuel, b for petrol, C for service type

Determine the value of B, define the value of price//By judging the different varieties of gasoline, define different unit prices

Determine the value of C, define the value of discount//define different discount ratios by judging different types of services

Calculate Money//Use Money = A * price * (1-discount) This formula calculates payables

Value of the output money

End

Topic Three: Comparison size

1. Experiment Code

#include <stdio.h>intMain () {inta,b,c,x,y,z; scanf (" %d%d%d",&a,&b,&c); if(A >b) {x=A; Z=b; }Else{x=b; Z=A; }    if(C >x) {x=C; }Else{        if(C <z) {Z=C; }} y= a + B + c-x-Z; printf ("%d->%d->%d", z,y,x); } 

2. Design Ideas

① algorithm

Begin

Input A,b,c

Determine the size of the value of a and B, assign the larger value to X, and the smaller value to Z. Defines x as the maximum value, z as the minimum, and y as the middle value

determine the size of the value of the larger and C values in a and B. If C is large, assign C to x.

Otherwise, determine if C is less than the smaller value in a and B. If so, assign C to Z.

The median y is the sum of three numbers minus the maximum and minimum values.

Output z->y->x

End

Topic Four: A simple calculator of two numbers

1. Experiment Code

#include <stdio.h>intMain () {intA,b,answer; CharC; scanf ("%d%c%d",&a,&c,&b); Switch(c) { Case '+': Answer= A +b; printf ("%d", answer);  Break;  Case '-': Answer= A-b; printf ("%d", answer);  Break;  Case '*': Answer= A *b; printf ("%d", answer);  Break;  Case '/': Answer= A/b; printf ("%d", answer);  Break;  Case '%': Answer= a%b; printf ("%d", answer);  Break; default: printf ("ERROR"); }    return 0;}

2. Design Ideas

① algorithm

Begin

Input a C B;//a, B is the input two integers, C is the operator

Determine why C is a symbol

If it is legal, calculate and output the results of A and B after this operator operation

If it is not legal, output error

3. In the first place, the switch statement was not used according to the job request, and the classmate reminded the amendment.

Initial if statement code:

#include <stdio.h>intMain () {intA,b,answer; CharC; scanf ("%d%c%d",&a,&c,&b); if(c = ='+') {Answer= A +b; printf ("%d", answer); }Else if(c = ='-') {Answer= A-b; printf ("%d", answer); }Else if(c = ='*') {Answer= A *b; printf ("%d", answer); }Else if(c = ='/') {Answer= A/b; printf ("%d", answer); }Else if(c = ='%') {Answer= a%b; printf ("%d", answer); }Else{printf ("ERROR"); }     }

Project

Personal Summary

First, this week's study content:

1. Learn the three loop statements of the while statement, the Do...while statement, the For statement, and learn the nesting of three loops in each other.

2. Learn the break statement and the continue statement.

3. Practice the IF statement and the switch statement to improve the proficiency of the statement application.

Second, doubtful points:

There is no more proficiency in the for statement, but it also requires practice.

Thirdly, there is no opinion on the present form of the teacher's class and cannot offer any advice.
