Question

用C语言编写程序统计三组字符串空格数的和

Answer 1

#include <stdio.h>
main()
{
char s1[10],s2[10],s3[10];
int sun=0;
int i;
puts(s1);
puts(s2);
puts(s3);
for(i=0,i<10,i++)
{
if(s1[i]==' ')
sum=sum+1;
if(s2[i]==' ')
sum=sum+1;
if(s3[i]==' ')
sum=sum+1;
}
printf("空格个数为%d个",sum);
}

Answer 2

#include <stdio.h>
int main()
{
char ch[3][1000];
int i,j,n=0;

printf("Input 3 string with space:\n");
gets(ch[0]);
gets(ch[1]);
gets(ch[2]);
for(i=0; i<3; i++)
{
for(j=0; ;j++)
{
if(ch[i][j]=='\0')
{
break;
}
else if(ch[i][j]==' ') n++;
}
}
printf("All space is %d\n", n);
return 0;
}
