#include #include using namespace std; int main() { //datatype for storing the scaned charecter char scannedcharecter; //filepointers for taking input inputfp and filepointer //outputfp to giveout output FILE *inputfp,*outputfp; //opening a file for reading and giving it to inputfp with read permissons inputfp = fopen("score.txt", "r"); //opening a file for writing and giving it to outputfp with write permissons outputfp = fopen("score.enc", "w"); //while loop for scannig charecter by charecter from the file and //break at the end of the file while (fscanf(inputfp, "%c", &scannedcharecter) != EOF) { //adding 50 to asci value for generating required asci value and printing its //symbol corresponding to that asci value in to the file fprintf(outputfp, "%c",int(scannedcharecter)+50); } //closing both the files fclose(inputfp); fclose(outputfp); return 0; }
