Alıştırma 2.b’ de hazırlamış olduğunuz C programına benzer şekilde, kaynak dosyadaki tüm küçük karakterleri büyüğe çevirerek hedef dosyaya kopyalama işlemini yapabilecek bir C programı hazırlayınız. Programınızda “islower”, “isupper”, “tolower” ve “toupper” fonksiyonlarını kullanmadan, karakterlerin ASCII değerlerinin hangi tamsayılara karşılık …
#include <stdio.h>
#include <stdlib.h>
int main()
{
char ch, source_file[20], target_file[20];
FILE *source, *target;
printf("Enter name of file to copy\n");
gets(source_file);
source = fopen(source_file, "r");
if( source == NULL )
{
printf("Press any key to exit...\n");
exit(EXIT_FAILURE);
}
printf("Enter name of target file\n");
gets(target_file);
target = fopen(target_file, "w");
if( target == NULL )
{
fclose(source);
printf("Press any key to exit...\n");
exit(EXIT_FAILURE);
}
while( ( ch = fgetc(source) ) != EOF )
ch=toupper(ch);
fputc(ch, target);
printf("File copied successfully.\n");
fclose(source);
fclose(target);
return 0;
}
