例输入两个数并判断两数相等否 Include <stdio.h> main int a. b: printf(" Enter integer a:"运行: Enter integer a12 scanf(%od", &a); Enter integer b: 12 printf( Enter integer b: a==b scanf(odor &b) if(a==b) 运行: Enter integer a:12 printf(a==bn) Enter integer b: 9 ese al=b printf("a!=bIn");
#include <stdio.h> main() { int a,b; printf("Enter integer a:"); scanf("%d",&a); printf("Enter integer b:"); scanf("%d",&b); if(a==b) printf("a==b\n"); else printf("a!=b\n"); } 例 输入两个数并判断两数相等否 运行：Enter integer a:12 Enter integer b:12 a==b 运行：Enter integer a:12 Enter integer b:9 a!=b
例判断输入字符种类 Include <stdio.h> main k char c; printf( Enter a character: ) c=getchar if(c<0x20) printf( The character is a control characterIn"); else if(c>=0&&c<=9) printf( The character is a digitin'") else if(c>='a'&&c<=z) printf( The character is a capital letterIn else if(c>=a&&c<=z)printf( The character is a lower letterin") else printf( The character is other characterIn); 运行: Enter a character:F1d The character is other character
#include <stdio.h> main() { char c; printf("Enter a character:"); c=getchar(); if(c<0x20) printf("The character is a control character\n"); else if(c>='0'&&c<='9') printf("The character is a digit\n"); else if(c>='A'&&c<='Z') printf("The character is a capital letter\n"); else if(c>='a'&&c<='z') printf("The character is a lower letter\n"); else printf("The character is other character\n"); } 例 判断输入字符种类 运行：Enter a character： The character is a control character ：8 The character is a digit 运行： Enter a character： D The character is a capital letter 运行： Enter a character： h The character is a lower letter 运行： Enter a character：F1 The character is other character
