CHAR Array - stuffed with values - with more size than it holds
Hi All
I am simulating a problem in the production where i faced a situation.
Please find the following example program which i simulated.


#include<stdio.h>

#include<stdlib.h>

#include<string.h>



int main()

{



char str1[20];

char str2[20];

double t1=0.0;

double output_value=888.00;

double count=0.0;

memset(str1,0x00,20);

memset(str2,0x00,20);

char output_str[20];

char output_str1[20];

memset(output_str,0x00,20);

memset(output_str1,0x00,20);

for(int i=0;i<50;i++) (Purposely specifying as 50 and not 20 as per the variable)

{

count=count+1.0;

sprintf(output_str, "%12.2f", count); (When str1 is exhausted i.e after 20th byte it is taking the value from str2 mentioned below)

strcat(str1,output_str);

strcat(str1, " ");

printf("The string length of str1=%d\n",strlen(str1));



if (i != 0)

output_value= 1 + output_value;

sprintf(output_str1, "%12.2f", output_value);

strcat(str2, output_str1);

strcat(str2, " ");



printf("The str1 has the value =%s\n\n",str1);

printf("The str2 has the value =%s\n\n",str2);



}



printf("\n\n\n The output line 3=%s\n",str1);







}



Please let me know if str1 is stuffed more than what it can hold, should it take the values from str2 ? as arrays are stored by contiguous memory location.

NOTES

       These are the classic themes you know from the famous books and tutorials.  However, they have flaws. Read the "booktabs" documentation for
       a discussion of this.

       The "plain" theme might be useful in combination with the ltpretty script.
