I am writing a C program that outputs a random hex value to a text file. The print value has a carriage return (CR) along with a line feed (LF). However, CR (visible in notepad ++) causes problems when using the file. Is there a way to print a new line only with LF and without CR.
This is the code:
#include <stdio.h> #include <stdlib.h> void main(){ int hexa_address, numberofAddress; char tracefile[50]; //name of file int seq_or_rand; //1 for random address; 2 for sequential address srand(time(NULL)); //reset the value of the random printf("This generator generates 32bits hexadecimal.\n\n"); printf("Name of file: "); scanf("%s", tracefile); printf("Random (1) or Sequential (2): "); scanf("%d", &seq_or_rand); FILE *file; file = fopen(tracefile,"w"); // create file if(seq_or_rand == 1){ //random generator file = fopen(tracefile,"w"); // create file for(numberofAddress = 0; numberofAddress<10000;numberofAddress++){ //create 10000 address //if(numberofAddress!=0) fprintf(file, "0 "); int space = 0; for(space; space<8; space++){ //remove any 0 from the left hexa_address = rand() % 16; if(hexa_address != 0){ fprintf(file,"%x", hexa_address); space++; break; } else if(hexa_address == 0 && space == 7){ //in condition of 00000000 fprintf(file, "0"); space++; } } for(space; space<8; space++){ //continue generating the remaining address hexa_address = rand() % 16; fprintf(file,"%x", hexa_address); } if(numberofAddress!=99999) fprintf(file,"\t"); //start a new line, but not on the last one } } else if(seq_or_rand == 2){ //sequential generator file = fopen(tracefile,"w"); // create file for(numberofAddress = 0; numberofAddress<10000;numberofAddress++){ //create 10000 address if(numberofAddress!=0) fprintf(file,"\n"); //start a new line, but not on the first one fprintf(file,"0 "); fprintf(file,"%x", numberofAddress*4); } } else{ //invalid input printf("Invalid Input"); exit(1); } fclose(file); //done }
