第一: #include<stdio.h> char str[1002]; int main() { int i; while(gets(str)!=NULL) { i=0; // while(str[i]!='\0') for(i=0;str[i]!='\0';i++) if(str[i]=='y'&&str[i+1]=='o'&&str[i+2]=='u') { printf("we"); i+=2; } else { printf("%c",str[i]); //i++; } printf("\0"); printf("\n"); } return 0; } 第二: #include<stdio.h> #include<string.h> char str[1002]; int main() { int i; while(gets(str)!=NULL) { i=0; while(str[i]!='\0') if(str[i]=='y'&&str[i+1]=='o'&&str[i+2]=='u') //短路,可以写道str[i+2] { printf("we"); i+=3; //printf("%d\n",i); } else { printf("%c",str[i]); i++; } printf("\0"); //必须是双引号 printf("\n"); } return 0; }
