Thread: string problem

Adding the '-' doesn't work. Please advise. Thank you.

char keys[100][30];
. . .

Code:

void printData(void)
{
    int x = 0;
    strcat(keys[x],"-");
    for(x = 0;x<cntr+1;cntr++) puts(keys[x]);
}

I retract my query. I have solved the problem by changing the code preceding what was displayed as the query code.

Hallo Ivory348

Look at line 5:
[code]
for(x = 0;x<cntr+1;cntr++) puts(keys[x]);
[code]
The integer 'x' has always the same content.
It can't get bigger.
The validity of 'x' is only for the function printData:
example:

Code:

#include <stdio.h>
#include <string.h>

#define NUMBER_OF_KEYS 15

void printData(char keys[NUMBER_OF_KEYS][30])
 {
  int x = 0;
           
    for(x = 0; x < NUMBER_OF_KEYS; x++) 
    {
     strcat(keys[x],"-");    
     puts(keys[x]);
    }
 }

void printData_b(char keys[NUMBER_OF_KEYS][30], char *test)
 {
  int x = 0;
           
    for(x = 0; x < NUMBER_OF_KEYS; x++) 
    {
     strcat(keys[x],test);    
     puts(keys[x]);
    }
 }

int main(int argc, char **argv)
{
 char keys[NUMBER_OF_KEYS][30] = {0};

 printf("strcat-test\n");
    
 printData(keys);
 
 printData_b(keys, "Tica'ti'bu");
    
 return 0;
}
