My code is not putting the text file data into line on the second pass of the while loop, and any subsequent pass. I'm sure it's a silly error but I cannot find it.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
FILE *fr;
char *line,*word,*vali;
ssize_t read;
int i=0,sum=0,len =0,flag=0;
const char delim[2]=" ";
int main(int argc, char* argv[])
{
line = (char *)malloc(sizeof(&len));
word = (char *)malloc(sizeof(&len));
vali = (char *)malloc(sizeof(&len));
fr = fopen(argv[1], "r");
if(fr==NULL)
{
exit(EXIT_FAILURE);
}
while ((read = getline(&line, &len, fr)) != -1)
{
printf("line is %s\n", line );
fscanf(fr,"%s%*[^\n]",word);
printf("%s ", word);
vali=strtok(line, delim);
while(vali != NULL)
{
sum=sum+atoi(vali);
vali = strtok(NULL, delim);
}
printf("%d\n", sum);
sum=0;
vali=" ";
len = strlen(line);
}
fclose(fr);
if (line)
free(line);
return 0;
}
malloc(sizeof(&len)). This doesn't look correct. What islen? It looks like you are allocating space for a pointer only.lenis defined as and initialized as?malloc()and family inC.len,line,word,validefined as? We could assume something and fix but, thats not the way this works. Please make sure that you put the code that can be compiled.
