C appears when executed, and what are the execution statements in C

There are a lot of problems. Such as overflow, missing library files, etc!!

#include

int main()

int i,j,n,a10011001,b10011001;

long m,max;

while(scanf("%d",&n)!=eof)for(i=1;i<=n;i++)for(j=1;j<=i;j++)scanf("%d",&aij);

for(i=0;i<=n;i++)

bi0=0;

bii+1=0;

for(i=1;i<=n;i++)for(j=1;j<=i;j++)if(bi-1j-1>bi-1j) m=bi-1j-1;else m=bi-1j;

bij=aij+m;

max=bn1;

for(i=2;i<=n;i++)if(bni>max) max=bni;

printf("%ld",max);

return 0;

Is this your **?

A large number of variables are not defined!

Possible causes: divided by 0, array out of bounds, pointer pointing wrong...

It's best to post ** to take a look.

See if the reference library file is missing.

Is the pointer being manipulated without being assigned?

Execute the statement for (i=1; i++<4;The value of the variable i is 5.

When i==3 (i becomes 4 after judgment), the condition is met and the loop is executed;

When i==4 (i becomes 5 after judgment), the condition is not met and the loop is exited.

i means that 1 is added first and then the comic value is assigned. When i changes to 4, 4<4 does not hold, but i=i+1 still executes, but does not execute the loop body. The cycle ends, so i finally changes to 5.

C statements can be divided into the following five categories:1expression statements; 2.

function invocation statements; 3.control statements; 4.compound statements; 5.

Empty statements. 1.Expression Statement: Expression Sentence Pronounced Sentence by Expression Semicolon"; "Composition.

Its general forms are: expression; Executing an expression statement is to calculate the value of the expression. For example:

x=y+z；a=520；assignment statements; y+z；Addition operation statements, but the calculation results cannot be retained, which has no practical significance; i++；Self-increment 1 statement, i value increase; It is to calculate i first and then add 1. ++i；The finch calendar always increases the i value by 1 and then calculates. Paragraph 2

The function call statement consists of the function name and the actual argument plus a semicolon"; "Composition. Its general form is: function name (actual parameter table); Executing a function statement is to call the function body and assign the actual parameters to the formal parameters in the function definition, and then execute the statement in the modulated function body to obtain the function value.

Call the library function and output the string. Paragraph 3Control statementsControl statements are used to control the flow of a program in order to implement various ways in which the program is structured.

They consist of specific statement definerents. The C language has nine control statements. It can be divided into the following three categories:

1).Conditional judgment statement if statement.
