====hello world====
#include <<stdio.h>>
int main()
====変数と算術式====
摂氏、華氏対応表
#include <<stdio.h>>
/* Convert temperature Celsius to Fahrenheit
F = 9/5 * C + 32 */
celsius = lower;
while (celsius <<= upper) {
fahren = celsius * 9 / 5 + 32;
printf("%d\t%d\n", celsius, fahren);
====For文====
摂氏、華氏対応表をForで書き直す
#include <<stdio.h>>
/* Convert temperature Celsius to Fahrenheit F = 9/5 * C + 32 */
int main() { int celsius;
for (celsius=0; celsius<<=300; celsius +=20) {
printf("%d\t%d\n", celsius, (celsius * 9 / 5 + 32));
}
*セミコロン不要
#include <<stdio.h>>
#define LOWER 0 /* lower limit of temperature */
int celsius;
for (celsius=LOWER; celsius<<=UPPER; celsius +=STEP) {
printf("%d\t%d\n", celsius, (celsius * 9 / 5 + 32));
}
