    problem with syntax for declaring array

    Code:
    //Plz sort out my problem
                                     
                                      #include<stdio.h>
    
    				  struct student
    				  {
    				  int num;
    				  char name[20];
    				  };
    
    			          int main(void)
    				  {
    				  struct student p;
    				  p.num=3;
    
    				  p.name="dilipkumar";          //whats wrong with this statement??
                                                                                      //how to initialise char array directly with string?
    				  FILE *fp;
    				  fp=fopen("cdk.txt","w");
    			          fwrite(&p,sizeof(struct student),1,fp);
    				  fclose(fp);
    			          return 4;
    				  }

    Code:
    p.name="dilipkumar";          //whats wrong with this statement??
    C doesn't allow to assign to an array.
    use strcpy()
    Code:
    strcpy(p.name,"dilipkumar");
    to initialize an array use

    Code:
    char arr[] = "dilipkumar";

    if you want to initialize a structure you could use
    Code:
        struct student s = {1, "joe"};

    the real trouble here is that you posted C code to the C++ forum.

    there is a difference.

    if this is C, then use the C forum.

    if it's C++ then use proper C++ constructs and functions. use std::fstream and std::string instead of FILE* functions and char pointers/arrays.

    if you have a book that claims to teach C++, but teaches you C first, then you immediately need to find a different book.
