Reading a text file, and performing actions based on strings read
- by user1691766
Let me start off by saying that I really am quite new to C.
So basically I have a text file (contains around 30 assembly instructions, separated by new lines), and I am successfully reading them into my program.
From here I need to perform certain actions based off each instruction. I would assume the best way to do this would be via a switch-case statement. However I am encountering a lot of problems due to me trying to compare strings that are 33 characters long.
Can anyone please offer me advice on what I am doing wrong, or offer an alternative? Thanks in advance.
Here is what I have so far:
char instruction[29][ 33 ];
int i,run;
i = 0;
run = 1;
FILE *instPtr;
/* LOADING INSTRUCTIONS FROM FILE INTO "instruction" ARRAY*/
if ( ( instPtr = fopen("MIPSinstructions.txt", "r") ) == NULL ) {
printf("File could not be opened\n");
} // end if
else {
fscanf( instPtr, "%s", instruction[0]);
printf("%s\n", instruction[0]);
while (!feof( instPtr ) ){
i++;
fscanf( instPtr, "%s", instruction[i]);
printf("%s\n", instruction[i]);
}
fclose( instPtr );
i = 0; // Reset the counter
} //end else
return 0;
}
