从键盘输入一个字符串 #includevoid main(){char str[256]；int i，k，n；gets(str)；键盘回车结束scanf(\"%s\"，str)键盘空2113格结束i=0；k=0；n=1；while(str[i]){if(str[k]>；str[i]){k=i；n=1；}else if(str[k]=str[i])n+；i+；}printf(\"字符5261值最小字符为4102%c，第1次出现位置%d，出1653现次数%d\\n\"，str[k]，k，n)；}
从键盘输入一个字符串， #includeint find(char*s，char c){int i；for(i=0；s[i]。e799bee5baa6e4b893e5b19e31333335313839=0；i+)if(s[i]=c)return i；return-1；}void delete(char*s，int idx){int i；for(i=idx；s[i]。0；i+)s[i]=s[i+1]；}void main(){char s[100]；char c；int idx；printf(\"Input a string：\")；gets(s)；printf(\"input a charactor：\")；scanf(\"%c\"，&c)；idx=find(s，c)；if(idx。1){printf(\"index=d\\n\"，idx)；delete(s，idx)；printf(\"after delete：%s\\n\"，s)；}else{printf(\"not find%c.\\n\"，c)；}}
从键盘怎么读入一个字符串，c语言中用gets #includeint main(void){char str[100]；printf(\"请输入5261一个字4102符串1653：\\n\")；gets(str)；printf(\"你输入了：%s\"，str)；}
