如何解决DECLARATION SYNTAX ERROR? [英] how to fix DECLARATION SYNTAX ERROR?
问题描述
#include < stdio.h >
#include < conio.h >
int main()
{
int i,j,a [ 3 ] [ 3 跨度>];
for (i = 0 ; i< 3; i ++)
{
for (j = 0 ; j< 3; j ++)
{
scanf( %d,& a [i] [j]);
}
}
// 没有转置的数组
// 显示
(i = 0 ; i< 3; i ++)
{
for (j = 0 ; j <3; j ++)
{
printf( %d,a [i]);
}
printf( / n);
}
// 转置后的数组
for (j = 0 ; j< 3; j ++))
{
printf( %d,& a [j]);
}
getch();
}
函数定义不是单个语句 - 它始终以大括号对开始和结束。
然后你在转换后的数组for循环中有一个虚假的)。
尝试:
#include < stdio.h >
#include < conio.h >
int main()
{
int i,j,a [ 3 ] [ 3 ];
for (i = 0 ; i< 3; i ++)
{
for (j = 0 ; j< 3; j ++)
{
scanf( %d,& a [i] [j]);
}
}
// 没有转置的数组
// 显示
(i = 0 ; i< 3; i ++)
{
for (j = 0 ; j <3; j ++)
{
printf( %d,a [i]);
}
printf( / n);
}
// 转置后的数组
for (j = 0 ; j< 3; j ++)
{
printf( %d,& a [j]);
}
getch();
}
但请帮个忙:一个字符变量名称很容易输入,但它们不会告诉你它们用于什么。对于这样一个简单的例子,这不是一个主要的问题,但如果你的课程开始建立在这个基础上,如果你使用描述数据而不是a的专有名称,它会变得非常有用。 / blockquote>
Quote:for(i = 0; i< 3; i ++)
{
for(j = 0; j< 3; j ++)
{
printf(%d,a [i ]);
}
printf(/ n);
}
//转置后的数组
for(j = 0; j <3; j ++))
{
printf(%d,& a [j ]);
}
应该是:
for (i = 0 ; i< 3; i ++)
{
for (j = 0 ; j< 3; j ++)
{
printf(跨度> <温泉n class =code-string>%d,a [i] [j]);
}
printf( / n);
}
// 转置后的数组
for (i = 0 ; i< 3; i ++)
{
for (j = 0 ; j< 3; j ++)
{
printf( %d,a [j] [i]);
}
printf( / n);
}
#include<stdio.h> #include<conio.h> int main() { int i,j,a[3][3]; for(i=0;i<3;i++) { for(j=0;j<3;j++) { scanf("%d",&a[i][j]); } } //Array Without Transpose //Display for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("%d",a[i]); } printf("/n"); } //Array After Transpose for(j=0;j<3;j++)) { printf("%d",&a[j]); } getch(); }解决方案A function definition is not a single statement - it always starts and ends with a curly bracket pair.
Then you have a spurious ")" in the "Array After Transpose" for loop.
Try:
#include<stdio.h> #include<conio.h> int main() { int i,j,a[3][3]; for(i=0;i<3;i++) { for(j=0;j<3;j++) { scanf("%d",&a[i][j]); } } //Array Without Transpose //Display for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("%d",a[i]); } printf("/n"); } //Array After Transpose for(j=0;j<3;j++) { printf("%d",&a[j]); } getch(); }
But do yourself a favour: one character variable names are easy to type, but they don;t tell you what they are used for. For a trivial example like this, it's not a major problem, but if your course starts to build on this, it can become very helpful if you use "proper names" that describe what the data is rather than "a" for example.
Quote:for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf("%d",a[i]);
}
printf("/n");
}
//Array After Transpose
for(j=0;j<3;j++))
{
printf("%d",&a[j]);
}
Should be instead:
for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("%d ",a[i][j]); } printf("/n"); } //Array After Transpose for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("%d ",a[j][i]); } printf("/n"); }
