How to read a textfile line by line to an array in c language?
its done by fgets() function in C
#include %26lt;stdio.h%26gt;
void stripnl(char *str) {
while(strlen(str) %26amp;%26amp; ( (str[strlen(str) - 1] == 13) ||
( str[strlen(str) - 1] == 10 ))) {
str[strlen(str) - 1] = 0;
}
}
int main()
{
FILE *infile;
char fname[40];
char line[100];
/* Read in the filename */
printf("Enter the name of a ascii file: ");
fgets(fname, sizeof(fname), stdin);
/* We need to get rid of the newline char. */
stripnl(fname);
/* Open the file. If NULL is returned there was an error */
if((infile = fopen(fname, "r")) == NULL) {
printf("Error Opening File.\n");
exit(1);
}
while( fgets(line, sizeof(line), infile) != NULL ) {
/* Get each line from the infile */
/* print the line number and data */
printf(" %s", line);
}
fclose(infile); /* Close the file */
}
