Segmantation fault when trying to access array of character pointers

Question

so i\'ve created a function that deals with a array of char pointers by using the [] operators. the function

int fetchargs(char **argv){
argv[0][0] = \'A\';              


        

Answer 1

char ** argv is a pointer to a pointer of character(s) or a double pointer
Where as argv[ARG_NUM][MAX_LINE] is essentially a 2D array of characters

Bottom line here is to Honor the Data Types

char argv[ARG_NUM][MAX_LINE];
.........
.........
int fetchargs(char argv[][MAX_LINE]){
  argv[0][0] = 'A'; 
  return 0;  
};
