请问c中未解析的外部符号这种咋解决啊

源代码
#include<stdio.h>#include<iostream.h>#include<stdlib.h>#define MaxInt 32767#define MVNum 100typedef char VerTexType;typedef int ArcType;typedef struct{ VerTexType vexs[MVNum]; ArcType arcs[MVNum][MVNum]; int vexnum,arcnum; }AMGraph;void GreateUDN(AMGraph &);int LocatexVex(AMGraph G,VerTexType u);void CoutGraph(AMGraph G);int main(){ AMGraph G; GreateUDN(G); CoutGraph(G);}void GreateUDN(AMGraph &G){ int i,j,k,v1,v2,w; cin>>G.vexnum>>G.arcnum; for(i=0;i<G.vexnum;i++) cin>>G.vexs[i]; for(i=0;i<G.vexnum;i++) for(j=0;j<G.vexnum;j++) G.arcs[i][j]=MaxInt; for(k=0;k<G.arcnum;k++){ cin>>v1>>v2>>w; i=LocatexVex(G,v1); j=LocatexVex(G,v2); G.arcs[i][j]=w; G.arcs[j][i]=G.arcs[i][j]; }}int LocateVex(AMGraph G,VerTexType u){ int i; for(i=0;i<G.vexnum;i++) if(u==G.vexs[i]) return i;}void CoutGraph(AMGraph G){ int i,j; for(i=0;i<G.vexnum;i++) for(j=0;j<G.vexnum;j++) cout<<G.arcs[i][j]<<endl;}

你这代码看着头疼 建议先修改下格式再问

把所有的LocatexVex替换为LocateVex
