You're using quotation tags, not code tags. Use ctrl-T to learn how to format code correctly, and use the "copy for forum" option in the IDE to paste here, it will look like this:
void setup() {
Serial.begin(115200);
int sis = 256 * 10;
float Main_Array = (float)malloc(sis * sizeof(float));
File myFile = SD_MMC.open("/jj.txt", FILE_READ);
if (myFile) {
Serial.println("Opening file to read failed");
return;
}
else {
Serial.println("File Content:");
while (myFile.available()) {
for (int i = 0; i <= 10; i++) {
Main_Array[i] = myFile.parseInt();
Serial.println(Main_Array[i]);
}
myFile.close();
}
}
}
void loop()
{
}
