Can some body help me change to C language?

[Cerav]

Does anyone know how to change this C++ to C? I'm having trouble doing it some pointers would be nice.

#include <iostream>
#include <string>
using namespace std;
typedef struct student {
char name[20];
char address[100];
char no[20];
}student;

typedef struct node{
student element;
node* next;
}node;

void print(student a){
cout<<"name : "<<a.name<<endl;
cout<<"address :"<<a.address<<endl;
cout<<"no : "<<a.no<<endl;
}
void printall(node* list){
node* cursor;
for(cursor=list;cursor!=NULL;cursor=cursor->next){
print(cursor->element);
}
}


void search(node* list){
char name[20];
cout<<"search name :";
cin>>name;
node* cursor;
node* follower=NULL;
for(cursor=list;cursor!=NULL;cursor=cursor->next){
if(!strcmp(name,cursor->element.name))
break;
follower=cursor;
}
if(cursor==NULL){
cout<<"student not found"<<endl;
follower=NULL;
}
else{
cout<<"student found :"<<endl;
print(cursor->element);
if(follower==NULL)
follower=cursor;
}
}
node* deletestudent(node* list){//follower-bye-a ---> follower-a
char name[20];
cout<<"delete name :";
cin>>name;
node* cursor;
node* follower=NULL;
for(cursor=list;cursor!=NULL;cursor=cursor->next){
if(!strcmp(name,cursor->element.name))
break;
follower=cursor;
}
if(cursor==NULL){
cout<<"student not found"<<endl;
follower=NULL;
return list;
}
else{
cout<<"student deleted "<<endl;
if(follower==NULL){
follower=cursor->next;
free(cursor);
return follower;
}else{
node* bye=follower->next;
follower->next=follower->next->next;
free(cursor);
return list;
}
}
}
node* insert(node* list){
char name[20];
char address[100];
char no[20];
cout<<"name : ";
cin>>name;
cout<<"address : ";
cin>>address;
cout<<"no : ";
cin>>no;

node* newNode=(node*) malloc(sizeof(node));
strcpy(newNode->element.name,name);
strcpy(newNode->element.address,address);
strcpy(newNode->element.no,no);
newNode->next=list;
return newNode;
}

int main(){
node* list=NULL;
int selection=0;
while(selection!=4){
cin>>selection;
switch(selection){
case 1:list=insert(list); break;
case 2:search(list); break;
case 3:list=deletestudent(list); break;
case 4:break;
case 5rintall(list);break;
}
cout<<endl;
}

}

On a quick cursory glance (since I'm in class now), the only part that probably needs changing are the cout cin. The C counterparts are scanf and printf (use the man pages to help you, or just google them). Be careful of buffer overflow exploits though, and use fscanf if you need extra security.
