(C언어) 기말고사

 빨리 집 내려가서 강아지도 보고 싶고 블로그나 영어공부하면서 좀 쉬고 싶은데,,, 스케줄이 있어서

그럼 시작해볼까요?

 

---

1.Define structure (book) with following members: title and pages. Declare book type of variable,  initialize the members to any values, and print it.

______________________________________________________________________4 points.

 

2. Declare float type of array (x) with size 5 and float type of pointer (p). Make the pointer point to array (p=x). Declare function as follows: void func (float *p). Pass your pointer to function  (func(p)). Your function should store any  five number on array through  the pointer p and print these numbers.

______________________________________________________________________6 point.

 

3. Declare function as follows: void func (char *p[3], int n). Declare char pointer array(char *p[3]) and store your name on it. Pass the pointer to function (func( p, n)). Your function should print nth name.

______________________________________________________________________8 points.

 

4. Declare function as follows: void func1 ( char *p). Declare char pointer and store any string. Pass the pointer to function (func1 (p)). Your function should count number the of all letters (a to z) and print the result.

_____________________________________________________________________12 points.

 

TOTAL: 30 points

1.Define structure (class) with following members: title and number of students. Declare class type of variable,  initialize the members to any values, and print it.

______________________________________________________________________4 points.

 

2. Declare float type of array (x) with size 5 and float type of pointer (p). Make the pointer point to array (p=x). Declare function as follows: void func (float *p). Pass your pointer to function  (func(p)). Your function should store any  five number on array through  the pointer p and print these numbers.

______________________________________________________________________6 point.

 

3. Declare function as follows: void func (char *p[3], int n). Declare char pointer array(char *p[3]) and store your name on it. Pass the pointer to function (func( p, n)). Your function should print the nth letter in each name.

______________________________________________________________________8 points.

 

4. Declare function as follows: void func1 ( int a[10]). Declare int type of array with the size 10 and store 10 numbers on it. The numbers should be between 1-10. Pass the array to function (func1 (p)). Your function should count the number the of all numbers (1 to 10) and print the result.

_____________________________________________________________________12 points.

 

TOTAL: 30 points

 

이렇게가 기말고사였거든요? 근데 분반이 2개라서 시험지도 두 개였기 때문에, 두 개 다 올려드렸습니다.

제 답이기 때문에, 불편한 부분이 있을 수도 있는데,, 맞긴 맞아용

#1. 기말 답

#include<stdio.h>
#include<string.h>
struct book{
	char title[1][20];
	int pages;
};

int main()
{
	int i, j, k;
	struct book b;
	for(int i=0; i<1; i++){
	gets(b.title[i]); //first
}
	scanf("%d", &b.pages);//second
	
	for(i=0; i<1; i++){
		for(j=0;j<20;j++){
			printf("%c", b.title[i][j]);
			if(b.title[i][j]=='\0')
			break;
		}
	}
	
	printf(" %d", b.pages);
	}

 

#2. 기말 답

#include<stdio.h>
void func(float *p){
	float x[5]={2.5, 3.5, 4.5, 5.5, 6.5};
	
	for(p=x; p<x+5; p++)
	printf("%f\n", *p);

}
int main(){
	float *p; 
	float x[5];
	
	p=x;
	func(p);
}

 

#3. 기말 답

#include<stdio.h>

void func(char *p[3], int n){
	
	char c[3];
	
	for(int i=0; i<3; i++){
		for(int j=0; *(p[i]+j)!='\0';j++){
			c[n-1]=*(p[i]+n-1);
		}
		printf("%c", c[n-1]);
	}

}
	
int main(){
	char *p[3]={"choi", "jin", "hyouk"};
	int n;
	
	printf("ENTER THE NUMBER(1/2/3)");
	scanf("%d", &n);
	
	func(p, n);
}

 

#4. 기말 답

#include<stdio.h>
void c_l(char *p){
	int i, j; 
	int count=0;
	char k;
	
	for(k=97; k<123; k++){
		for(i=0; *(p+i)!='\0'; i++){
				if(*(p+i)==k)
				count++;
			}
	printf("%c의 개수는 %d\n", k, count);
	count=0;
}
	}

int main(){
	char *p={"choijinhyouk"};
	c_l(p);
}

이상 기말이었습니다~~~~ 이제 남은 부분은 기말 이후 부분과 제가 c로 이벤트처리하는 부분을 좋아했어서 여러 게임을 만들었는데, 그것을 설명해드릴 예정입니다. 이는 이제 python, java부분이 끝나면 하지 않을까...? 싶네요 java 이벤트를 쓰고 나서부턴 C언어는 손도 안 댔다는...

여러분 그러면 C프로그래밍 응용으로 돌아올게요
