例求一个数的绝对值 井 include< stdio. h> main int x,y5 printf( " Enter an integer scanf(%d", &x); y-x, if(y<0) printf(integer: %od--->absolute value: %d\n"x, y); 运行: Enter an integer:12 integer: -12--->absolute value: 12
#include <stdio.h> main() { int x,y; printf("Enter an integer:"); scanf("%d",&x); y=x; if(y<0) y= -y; printf("\ninteger:%d--->absolute value:%d\n",x,y); } 例 求一个数的绝对值 运行：Enter an integer:-12 integer:-12--->absolute value :12
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
