1. To achieve the following function, if the parameter is greater than 10, greater than 10 is printed, or printing is less than 10

void is_larger_then_10(int val);

Solution: (* prov-then.c)

void is_larger_then_10(int val){
	if(val>10){
		printf("larger then 10\n");
	}else{
		printf("smaller then 10\n");
	}
}

2. To achieve the following function, if the string like "abc", the print find abc, or do not print any information void is_find (char * str);

Solution: (* prov-print.c)

void is_find(char *str){
	if(0==strcmp(str,"abc")){
		printf("find abc");
	}
}

3. What is the difference between the following two functions

void f1()
{
printf("hello");
}

void f2()
{
printf("hello\n");
}

Solution: (* Note)

\ n: 1) Wrap;
2) printf content is stored in the buffer encounter \ n can be printed out directly.

4. implement a function, initialize the following structure

struct Area { int x;
int y;
struct Area *next;
};
void init_area(struct Area *area);

Solution: (* Note moderation, simply direct initialization prov-struct.c)

struct Area { 
int x;
int y;
struct Area *next;
};
void init_area(struct Area *area){
	area->x=1;
	area->y=2;
	area->next=NULL;

}

5. Implement mystrcpy

char *mystrcpy(char *dst, char *src);

Solution: (* Note # prov-strcpy.c)

char *mystrcpy(char *dst, char *src){
	char *p=dst;		//保存dst的首地址
	while(*src!='\0'){		//结束条件
		*dst++=*src++;
	}
	*dst='\0';		//结束符'\0'
	return p;
}

Summary: The fifth question the need to strengthen control, the first time to write some some small problems, keep in mind three steps.

Please disregard the above solution behind the brackets! ! ! Just make a mark only, no other meaning.
