Add a display conversion - before braces (person), if not support, in the tools - compile options, compile or link command, add open or C11 C99 standard, such as - STD=C11

CodePudding user response:

The person x [3]={{xx, xx, xx, xx},
{xx, xx, xx, xx},
{xx, xx, xx, xx}.};
It can be initialized

CodePudding user response:

Assignment problem, such assignment is generally at the time of initialization, or a member of the structure need a structure member assignment;

Person x [3]={{}, {}, {}};
The initialization of the three members together;

Or

X [0]. Num=1;
Strcpy (x [0]. The name "Alice");
.
The same as below

CodePudding user response:

I can't write this assignment in the image, the initialization can use it only when,
Written
Person x [3]={{... }, {... }, {... }};
. Is [0], x x [1], [2] x content, so give it a try

Reference:

 typedef struct Person {
Int num. 
Char name [20]. 
Int sex; 
Char group; 
Int score1. 
Int score2; 
Int score3; 
} person; 


Int main (int arg c, char * argv []) 
{
The person x [3]={
{1, "Alice", 0, 'A', 90,77,95}, 
{2, "Tony", 1, 'B', 92,78,93}, 
{3, "Tom", 1, 'C', 87,90,78} 
}; 
int i; 
for(i=0; i<3; I++) 
Printf (" % d % s c % d % d % d % d % \ n ", x [I] num, x [I]. Name, x [I] sex, x [I] group, x [I] score1, x [I] score2, x [I] score3); 
system("pause"); 
return 0;
