You can make a two-dimensional [plastic or char type] array, and the number of rows and columns is the number of rows and columns on the screen. Then, you can calculate the value of the element in the corresponding position, and then print out the array elements (take the char type as an example here):

# include & ltstdio.h & gt

# include & ltmath.h & gt

# include & ltstdlib.h & gt

# Define Line 25

# Define the 84th column

Char table [row] [column];

void initTable()

{

for(int I = 0； I< platoon; i++)

{

for(int j = 0； j & ltCOLj++)

{

Table [I] [J] = "";

}

}

}

int main(int argc，char*argv[])

{

//Take cos(x) as an example.

//Because the number of rows and columns is variable, the expected result is rounded down here.

//The abscissa position here is the 20th line.

//Draw the x and y coordinates first.

for(int row = 0； Row< row; row++)

{

table[row][0]= ' | '；

}

table[20][0]= '+'；

for(int col = 1； col & ltCOLcol++)

{

Table [20][ Column] ='-';

}

Table [0] [0] ='';

table[20][COL- 1]= ' >；' ;

//Here, use X to calculate the value of cos, and use' *' to replace the characters at the corresponding coordinates;

for(int x = 0； x & ltCOL- 1； x++)

{

table[5 *(int)(cos(x))][x]= ' * '；

}

//The next step is to output line by line.

for(int I = 0； I< platoon; i++)

{

for(int j = 0； j & ltCOLj++)

{

printf("%c "，table[I][j])；

}

}

System ("suspended");

}
