There was a problem C language output-CodePudding

In the console output program error, input data from ten students finish the first line of input ready to enter the next line, but a press enter the program ended, please help solve it

CodePudding user response:

Only one line of input

reference 1st floor space to the breeze full building response:

only one line of input

(????? ) I opened to, this code should be the branch information input ten students, as a result of the input a press enter is over

Your source code?

The scanf is getting out, your input and it does not match the demand, it is angry,

This is the code # include

Said the problem of input is the light
Scanf_s (" % d % s % f % f % f ", & amp; Stu [I]. Num, stu [I]. Name, 19, & amp; Stu [I] score [0], & amp; Stu [I] score [1], & amp; Stu [I] score [2]);

Delete a & amp; , you know,
Added a 19, this is the suffix _s scanf_s extra small temper,

CodePudding user response:

To search the scanf_s () function usage, here under the input function changed, no trouble, for reference:

 
Void input (struct Student stu [])//define input function 
{
int i; 
Printf (" please input the student's information: student id, name, 3 course results: \ n "); 
For (I=0; I & lt; N; I++) 
{
The scanf (" % d % s % f % f % f ", 
& Stu [I]. Num, & amp; Stu [I]. Name, & amp; Stu [I] score [0], & amp; Stu [I] score [1], & amp; Stu [I] score [2]);//input data 
Stu [I] aver=(stu [I] score stu [0] + [I] score [1] + stu [I] score [2])/3.0; Average score//o 
} 
}

The running effect is as follows, chose three input:

The scanf_s don't have space in brackets,
