The program is working fine now, just needed to close the file and open again to read the data. Ty for the help everyone!

Another error, sorry :/ I changed to 'n' and &op[i] and all the warnings are gonne! :) The programs runs perfectly but all the values of vector op[] are == 0. ex:

printf("%d\n%d", op[4], op[5]);

The answer still

0
0

I'm really thankful! :D

Thank you! You help me a lot! But the compiler still having problem to count lines and fscanf the data I need, I don't have a clue what is going on--'

Thank you! I didn't see that error of logic... --' But still giving me the same answer :/ I think the error is when he count the lines on

char n;
while (!feof(arq1)) {
n = fgetc(arq1);
if (n == "\n") { //count lines
ct++;
}
}

warning: assignment makes pointer from integer without a cast and...

for(i=0;!feof(arq1);i++) {
fscanf(arq1, ",,,%d,", op[i]); //I think this is the error
}

format ‘%d’ expects argument of type ‘int *’, but argument 3 has type ‘int’ [-Wformat=]|

gcc -c "trabalho.c" -o "trabalho.o"

When I compile the .c archive, appears just those 2 warnings

#include #include #include int main(int *op[]) {
char n;
int total;
int ct = 0, oper1 = 0, oper2 = 0, oper3 = 0, i = 0;
FILE *arq1;

arq1 = fopen("Maq1.log", "r"); //open file
while (!feof(arq1)) {
n = fgetc(arq1);
if (n == "\n") { //count lines
ct++;
}
}
op = (int*) calloc(ct, sizeof(int)); //alloc memory
if(op==0) {
printf("Não houve memoria alocada!\n");
return 0;
}
for(i=0;!feof(arq1);i++) {
fscanf(",,,%d,", &op[ct]); //I think this is the error
}
for(i=0;i<=ct;i++) { //do the count
if(op[ct] == 1){
oper1++;
}
if(op[ct] == 2){
oper2++;
}
if(op[ct] == 3){
oper3++;
}
}
total = oper1 + oper2 + oper3;
printf("Operacao 1: %d \n Operacao 2: %d \n Operacao 3: %d \n Total: %d \n", oper1, oper2, oper3, total); //and print!
fclose(arq1);
return 0;
}

Can you guys help me on this Code? I have no idea of what is happening, but when I run the code he prints

Operacao 1: 0
Operacao 2: 0
Operacao 3: 0
Total: 0

Sorry for the bad english!
