第十次作业

拆分实数

#include "stdio.h"
int main(void)
{
double x, y, z, *intpart = &y, *fracpart = &z;
void splitfloat(double x, double *intpart, double *fracpart);
printf("输入一个小数:");
scanf("%lf", &x);
splitfloat(x, intpart, fracpart);
printf("The intpart is: %lf ", *intpart);
printf("The fracpart is:%.6lf ", *fracpart);
return 0;
}
void splitfloat(double x, double *intpart, double *fracpart)
{
*intpart = (int)x;
*fracpart = x - *intpart;
}

在数组中查找指定元素

#include <stdio.h>
int search(int list[],int n,int x)
{
int i;
for(i=0;i<n;i++)
if(list[i]==x)return i;
else return -1;
}
main()
{
int list[10],n,x,i;
printf("输入一个正整数n(1<n<=10):");
scanf("%d",&n);
printf("输入%d个数: ",n);
for(i=0;i<n;i++)
scanf("%d",&list[i]);
printf("输入x:");
scanf("%d",&x);
if(search(list,n,x)==-1)printf("N0T Found ");
else printf("%d ",search(list,n,x));
}

 删除字符

#include"stdio.h"
#include"string.h"
void delchar(char* a,char* b,char c);
int main(void)
{
char a[100];
char b[100];
char c;
printf("Input the string:");
scanf("%s",a);
printf("Input a ch:");
scanf("%s",&c);
delchar(a,b,c);
printf("%s",b);
printf(" ");
return 0;
}
void delchar(char* a,char* b,char c)
{
int i=0,j=0;

while(a[i]!=''){
if(a[i]!=c){

b[j]=a[i];

j++;}
i++;
}
b[j]=''; }

 

字符排序

#include <stdio.h>
#include <string.h>

void m(char *p[])

{
int i,j,k;
char *t;
for (i=0; i<4; i++) {
for (j=0; j<4-i; j++) {
if (strcmp(p[j],p[j+1])>0) {
t=p[j];
p[j]=p[j+1];
p[j+1]=t;
}
}
}

for (k=0; k<5; k++) {
puts(p[k]);
}

}

int main()
{
printf("请输入5个数:");
int i;
char a[5][80];
char *p[5];
for (i=0;i<5; i++) {
scanf("%s",&a[i]);
p[i]=a[i];
}
m(p);
return 0;
}
