c - I have an issue printing the length of a string from the command line without using strlen? -

hello there program meant when user enters string command line print word , size.

e.g

./commandline hello world 

output:

hello

world

2

what i'm trying add method print length without using strlen output should length 10 example above.

this code bare in mind new c.

int main(int args, char *argv[]){      for(int =1; <args; i++){         printf("%s\n", argv[i]);         size_t(argv[i]);      }      printf("%d\n", args -1); } size_t string_length( char *argv[]){     int length = 0;     while(argv[length]!='\0')       {         length++;         printf("%i\n", length);     }     return 0; } 

my program not print length prints string entered , size.

 for(int =1; <args; i++){      printf("%s\n", argv[i]);      size_t(argv[i]);  }  printf("%d\n", args -1); 

here you're not calling function anywhere. program prints arguments , number of them. size_t(argv[i]); merely casts argv[i] type called size_t. certainly, that's not want. replace string_length(argv[i]);. note you'd better change type of first argument of function.

what's more, should return length in string_length function.

size_t string_length( char *arg){     size_t length = 0;     while(arg[length])       {         length++;     } return length; }
