The C language-CodePudding

I want to return pointer function is used to judge the mo some classmates failed the individual subject, and to output their student number, grade, but I don't this always lose out as a result, hope bosses to give directions, thank you

# include "stdio.h"
Int main ()
{
Float grade [] [4]=60,70,80,90,56,89,67,88,34,78,90,66 {};//store performance
Float * search (float (* pointer) [4]);
Float * p;
int i,j;
for(i=0; i<3; I++)
{
P=search (grade a + I);
If (p==* (grade a + I))
Printf (" No. % d ", I);//output student id
for(j=0; j<4. J++)
Printf (" % 5.2 f ", * (p + j));//output meet the conditions of student achievement
printf("\n");
}
}
Float * search (float (* pointer) [4])
{
Float * pt;
int i=0;
Pt=NULL;
for(; i<4. I++)
If (* (* pointer + I) & lt; 60) pt=* pointer;
Return pt;
}

Reference:

 # include "stdio.h" 

Int main (int arg c, char * argv []) 
{
Float grade [] [4]=60,70,80,90,56,89,67,88,34,78,90,66 {};//store performance 
Float * search (float (* pointer) [4]); 
Float * p; 
int i,j; 
for(i=0; i<3; I++) 
{
P=search (grade a + I); 
If (p) {//if (p==* (grade a + I)) {
Printf (" No. % d ", I + 1);//output student id 
for(j=0; j<4. J++) 
Printf (" % 6.2 f ", * (* (grade a + I) + j));//output meet the conditions of student achievement 
printf("\n"); 
} 
} 

//system (" pause "); 
return 0; 
} 


Float * search (float (* pointer) [4]) 
{
Float * pt; 
int i; 
Pt=NULL; 
for(i=0; i<4. I++) 
If (* (* pointer + I) & lt; 60) pt=(* pointer + I); 
Return pt; 
}

The method of the building Lord:

 # include "stdio.h" 
Int main () 
{
Float grade [] [4]=60,70,80,90,56,89,67,88,34,78,90,66 {};//store performance 
Float * search (float (* pointer) [4]); 
Float * p; 
int i,j; 
for(i=0; i<3; I++) 
{
P=search (grade a + I); 
If (p==* (grade a + I)) {
Printf (" No. % d ", I + 1);//output student id 
for(j=0; j<4. J++) 
Printf (" % 6.2 f ", * (p + j));//output meet the conditions of student achievement 
printf("\n"); 
} 
} 

//system (" pause "); 
return 0; 
} 


Float * search (float (* pointer) [4]) 
{
Float * pt; 
int i; 
Pt=NULL; 
for(i=0; i<4. I++) 
If (* (* pointer + I) & lt; 60) pt=* pointer; 
Return pt;
