C 編寫一函數(shù)，比較兩個字符串的大小，不能用strcmp？

#include<iostream>#include<cstring>usingnamespacestdintstr_len(char*a){intifor(i=0a[i]!="0"i )returni}intstr_cmp(char*a，char*b){inta_size=str_len(a)intb_size=str_len(b)if(a_size>b_size)return1elseif(a_size<b_size)return-1else{for(inti=0i<a_sizei ){if(a[i]>b[i])return1elseif(a[i]<b[i])return-1}}return0}intmain(){chara_1[10]="pause"chara_2[10]="Pause"charb_1[10]="hello"charb_2[10]="ahh"cout<<"str_cmp:"<<str_cmp(a_1，a_2)<<"t"cout<<"strcmp:"<<strcmp(a_1，a_2)<<endlcout<<"str_cmp:"<<str_cmp(b_1，b_2)<<"t"cout<<"strcmp:"<<strcmp(b_1，b_2)<<endlcout<<"str_cmp:"<<str_cmp(a_1，b_2)<<"t"cout<<"strcmp:"<<strcmp(a_1，b_2)<<endlcout<<"str_cmp:"<<str_cmp(a_2，b_1)<<"t"cout<<"strcmp:"<<strcmp(a_2，b_1)<<endlsystem("pause")return0}測試數(shù)據(jù)比較少，麻煩LZ自己出吧
